Opfindelsen angår hidtil ukendte, kemiluminescerende acridinderivater og en fremgangsmåde til deres fremstilling.The invention relates to novel chemiluminescent acridine derivatives and to a process for their preparation.
Luminescerende forbindelser finder allerede mangesidig anvendelse. De anvendes som indikatorer ved bioanalyser, 5 enzymimmunanalyser og luminescensimmunanalyser (jfr. W.P. Collins "Alternative Immunoassays", forlag John Wiley & Sons Ltd., Chichester, 1985), men de anvendes også ved nuclein-syre-hybridiseringsanalyser (jfr. J.A. Matthews et al. "Analytical Biochemistry", 151, 205-209, 1985). Desuden 10 anvendes kemiluminescerende forbindelser ved "flow injection analysis", til detektorer, der er indskudt efter kolonnen ved væskechromatografi, i strømningsforskningen og i kunstige lyskilder.Luminescent compounds are already widely used. They are used as indicators in bioassays, 5 enzyme immunoassays and luminescence immunoassays (cf. WP Collins "Alternative Immunoassays", publisher John Wiley & Sons Ltd., Chichester, 1985), but they are also used in nucleic acid hybridization assays (cf. JA Matthews et al. "Analytical Biochemistry", 151, 205-209, 1985). In addition, chemiluminescent compounds are used in "flow injection analysis", for detectors inserted after the column by liquid chromatography, in the flow research and in artificial light sources.
Ved kemiluminescensimmunanalyserne har især to struk-15 turtyper af kemiluminescerende mærkningssubstanser opnået større betydning. Det drejer sig her på den ene side om luminol- og isoluminolderivaterne, der er beskrevet af H.R. Schroeder et al., "Methods in Enzymology", Academic Press Inc., New York, vol. LVII, 1978, side 424 ff, samt i GB-20 -patentskrifter nr. 2.008.247 og 2.041.920 og i DE-patent-skrifter 2.618.419 og 2.618.511, samt i EP-offentiiggørelses-skrift nr. 135.071. Man får et overblik over den praktiske anvendelse af isoluminolforbindelserne som luminescensindikatorer hos W.G. Wood, J. Clin. Chem. Clin. Biochem. 22, 25 1984, side 905-918.In chemiluminescence immunoassays, in particular, two structural types of chemiluminescent labeling substances have gained greater importance. Here, on the one hand, these are the luminol and isoluminol derivatives described by H.R. Schroeder et al., "Methods in Enzymology", Academic Press Inc., New York, Vol. LVII, 1978, pages 424 et seq., And in GB-20 Patent Nos. 2,008,247 and 2,041,920 and in DE Patent Nos. 2,618,419 and 2,618,511, as well as in EP Publication No. 135,071. An overview of the practical use of the isoluminol compounds as luminescence indicators by W.G. Wood, J. Clin. Chem. Clin. Biochem. 22, 25 1984, pages 905-918.
På den anden side har også acridiniumesterforbindelser fundet anvendelse som kemiluminescerende mærkningssubstanser. Sådanne acridiniumestere kendes fra US-patentskrift nr. 3.352.791, GB-patentskrifter nr. 1.316.363 og 1.461.877 30 samt fra EP-offentiiggørelsesskrift nr. 82.636. Anvendelsen af acridiniumestere som mærkningssubstanser i immunanalyser er beskrevet af Weeks et al., Clin. Chem. 29/8 (1983), 1474--1479. Også anvendelsen af phenanthridiniumestere som mærkningssubstans i luminescensimmunanalyser er kendt fra EP-35 -offentliggørelsesskrift nr. 170.415.On the other hand, acridinium ester compounds have also been used as chemiluminescent labeling substances. Such acridinium esters are known from U.S. Patent Nos. 3,352,791, GB Patent Nos. 1,316,363 and 1,461,877, and from EP Publication No. 82,636. The use of acridinium esters as labeling substances in immunoassays has been described by Weeks et al., Clin. Chem. 29/8 (1983), 1474--1479. Also, the use of phenanthridinium esters as labeling substance in luminescence immunoassays is known from EP-35 Publication No. 170,415.
Kemiluminescensen fra acridiniumestere kan startes 2 DK 171437 B1 ved tilsætning af en basisk H202-opløsning. For kemilumi-nescensens mekanisme har F. McCapra, Acc. Chem. Res. 9, 201, 1976, givet en overbevisende forklaring. Derved er den fraspaltelige gruppes art tydeligvis afgørende for såvel lys-5 kvanteudbyttet som for den hydrolytiske stabilitet.The chemiluminescence from acridinium esters can be started by adding a basic H 2 O 2 solution. For the mechanism of chemiluminescence, F. McCapra, Acc. Chem. Res. 9, 201, 1976, given a convincing explanation. Thus, the nature of the leaving group is obviously crucial for both light quantum yield and hydrolytic stability.
De hidtil kendte acridiniumestere har fordelen af et højere lyskvanteudbytte i forhold til luminol- og isoluminol-forbindelserne, og lyskvanteudbyttet bliver heller ikke påvirket uheldigt af proteiner, der er bundet til indikatoren 10 (jfr. Weeks et al., Clin. Chem. 29/8 (1983), 1474-1479).The known acridinium esters have the advantage of a higher light quantum yield over the luminol and isoluminol compounds, and the light quantum yield is also not adversely affected by proteins bound to the indicator 10 (cf. Weeks et al., Clin. Chem. 29 / 8 (1983), 1474-1479).
Skønt de fra EP-offentliggørelsesskrift nr. 82.636 kendte acridiniumphenylestere ved stimulering af kemiluminescensen ved hjælp af milde oxidationsmidler udmærker sig ved en stor påvisningsfølsomhed, udviser de forstyrrende 15 ulemper ved den praktiske anvendelse. Frem for alt er phenyl-esterbindingen i vandige systemer også allerede meget labil ved stuetemperatur. Hertil kommer, at acridiniumphenylesteren under de der angivne oxidationsbetingelser har en lysemission, der først forsvinder efter ca. 10 sekunder i stor ud-20 strækning, dvs. op til over 95%. 1 sammenligning hermed har andre ikke-isotopiske analysefremgangsmåder meget kortere måletider og herved gives mulighed for en større prøvekapacitet.Although the acridinium phenyl esters known from EP Publication No. 82,636 known to stimulate chemiluminescence by means of mild oxidants are characterized by a high detection sensitivity, they exhibit disruptive drawbacks in the practical application. Above all, the phenyl ester bond in aqueous systems is also already very labile at room temperature. In addition, under the oxidation conditions stated, the acridinium phenyl ester has a light emission that disappears only after approx. 10 seconds in large extent, ie. up to over 95%. In comparison, other non-isotopic assay methods have much shorter measurement times and thus allow for a larger sample capacity.
Det er derfor formålet med den foreliggende opfindelse 25 at tilvejebringe hidtil ukendte, kemiluminescerende acridi-niumderivater, der på grund af et større lyskvanteudbytte har en hurtigere reaktionskinetik, og dermed muliggøres korte måletider ved en luminescensimmunanalyse.It is therefore the object of the present invention to provide novel chemiluminescent acridium derivatives which, due to greater light quantum yield, have a faster reaction kinetics, thus enabling short measurement times by luminescence immunoassay.
Dette formål er opnået med de her omhandlede, kemi-30 luminescerende acridiniumderivater, som er ejendommelige ved, at de har den almene formel IThis object has been achieved with the above-described chemiluminescent acridinium derivatives, which are characterized in that they have the general formula I

Θ nævnte substituenter desuden kan betyde hydrogen, og A er en anion, der ikke påvirker kemiluminescensen.Subst said substituents may also mean hydrogen and A is an anion that does not affect chemiluminescence.
Blandt substanserne af biologisk interesse forstås 5 frem for alt antigener. Under dette begreb hører også hormoner, steroider, lægemidler, lægemiddelmetabolitter, toxi-ner, alkaloider og også antistoffer.Among the substances of biological interest are 5 above all antigens. This term also includes hormones, steroids, drugs, drug metabolites, toxins, alkaloids and also antibodies.
Den anion, der ikke påvirker kemiluminescensen uheldigt, kan være en tetrafluorborat-, perchlorat-, halo-10 gen-, alkylsulfat-, halogensulfonat-, alkylsulfonat- eller arylsulfonat-anion. Også enhver anden anion kan anvendes, såfremt den ikke hindrer eller svækker kemiluminescensen.The anion which does not adversely affect the chemiluminescence may be a tetrafluoroborate, perchlorate, halogen, alkyl sulfate, halogen sulfonate, alkyl sulfonate or arylsulfonate anion. Also, any other anion can be used if it does not hinder or impair chemiluminescence.
Ved aryl forstås aromatiske carbonhydrider, især phenyl og naphthyl. Når sådanne grupper indeholder hetero-15 atomer, er der tale om et nitrogen- eller oxygenatom, især quinolin, indol, pyrrol og pyridin. Ved halogener forstås fluor, chlor, brom og iod.By aryl is meant aromatic hydrocarbons, especially phenyl and naphthyl. When such groups contain heteroatoms, it is a nitrogen or oxygen atom, especially quinoline, indole, pyrrole and pyridine. Halogens are fluorine, chlorine, bromine and iodine.
De substituerede aminogrupper er C^-C^-alkyl- eller C^-C^dialkylaminer, hvor alkylgrupperne kan være monosubs-20 titueret med hydroxy. Ligeledes kan der være tale om en morpholingruppe. De ved R2 og R3 angivne alkoxygrupper har 1-4 C-atomer i alkyldelen.The substituted amino groups are C ^-C ^ alkyl or C ^-C ^ dialkylamines wherein the alkyl groups may be monosubstituted with hydroxy. Likewise, there may be a morpholine group. The alkoxy groups represented by R 2 and R 3 have 1-4 C atoms in the alkyl moiety.
I almindelighed vælges acridiniumderivater, i hvilke X betyder en methylen-, ethylen-, propylen- eller en or-25 tho-, metha- eller para-phenylengruppe. Til forbedring af acridiniumderivaternes vandopløselighed kan disse grupper også have hydrofile substituenter, der indeholder hetero-atomer.Generally, acridinium derivatives are selected in which X represents a methylene, ethylene, propylene or an ortho, metha or para-phenylene group. To improve the water solubility of the acridinium derivatives, these groups may also have hydrophilic substituents containing heteroatoms.
Af særlig betydning for anvendelsesmulighederne af 30 acridiniumderivaterne ifølge opfindelsen er substituenten R5. Gennem et egnet valg af denne gruppe får acridinderi-vatet en så stor reaktivitet, at det under skånende betingelser selektivt kan indgå en binding med en funktionel gruppe i den biologiske substans, der skal påvises. Egnede 35 reaktive grupper ses af den følgende opstilling: 5 DK 171437 B1Of particular importance to the uses of the 30 acridinium derivatives of the invention is the substituent R5. Through a suitable choice of this group, the acridine derivative gains such a high reactivity that under sparing conditions it can selectively enter into a bond with a functional group in the biological substance to be detected. Suitable 35 reactive groups are seen in the following arrangement: 5 DK 171437 B1

Ved foreliggende opfindelse tilvejebringes to hidtil ukendte klasser af acridiniumforbindelser, hvor den ene klasse indeholder en thiolestergruppering og den anden en sulfonamidstruktur. I forhold til de kendte acridiniumphenyl-25 ester-forbindelser har acridiniumacylsulfonamid-derivaterne en større stabilitet, og både disse derivater og thiolesteme har en hurtigere kinetik. Begge forbindelsesklasser udmærker sig desuden ved et større lysudbytte.The present invention provides two novel classes of acridinium compounds, one class containing a thiol ester group and the other a sulfonamide structure. Compared to the known acridinium phenyl ester compounds, the acridinium acylsulfonamide derivatives have a greater stability, and both these derivatives and the thiol esters have a faster kinetics. Both connection classes are also distinguished by a greater light output.
En betydelig fordel ved de acridiniumforbindelser 30 ifølge opfindelsen, der indeholder thiolesterholdige, fraspaltelige grupper, i forhold til de fra den EP-offentiiggø-relsesskrift nr. 82.636 kendte acridiniumphenylestere ligger i lysemissionens væsentligt hurtigere reaktionskinetik. Således giver den efter eksempel 1 fremstillede acridinium-35 thioester ifølge opfindelsen (forbindelse 6) ved en måletid på 1 sekund, et lysudbytte, der er en faktor 10 større under de samme oxidationsbetingelser. Disse store lysudbytter samtidig med korte måletider muliggør en væsentlig større 8 DK 171437 B1 prøvekapacitet i luminometeret.A significant advantage of the acridinium compounds 30 of the invention, which contain thiol ester-containing leaving groups, over the acridinium phenyl esters known from EP Publication No. 82,636 are in the substantially faster reaction kinetics of the light emission. Thus, the acridinium thioester of the invention (Compound 6) prepared according to Example 1, at a measurement time of 1 second, gives a light yield which is a factor 10 greater under the same oxidation conditions. These large light yields, together with short measurement times, allow for a significantly larger sample capacity in the luminometer.
Således viser fig. 1 kinetikken af lysemissionen af et antistofkonjugat af en ifølge eksempel l fremstillet acridiniumthioester (forbindelse 6), og fig. 2 viser kine-5 tikken af lysemissionen af et antistofkonjugat af 4-(2-suc-cinimidyl-oxycarbony lethyl) phenyl-10-methylacridinium-9-carboxylat-methosulfat (EP-of fenti iggørelsesskrift nr. 82.636, side 10). 100 μΐ af hver af traceropløsningerne stimuleres ved tilsætning af 350 μΐ 0,05 M KCl/NaOH-puffer 10 pH 13 + 0,1% H2O2 til kemiluminescens, og der registreres over et tidsrum på 10 sekunder.Thus, FIG. 1 shows the kinetics of the light emission of an antibody conjugate of an acridinium thioester prepared according to Example 1 (compound 6); and FIG. Figure 2 shows the kinetics of the light emission of an antibody conjugate of 4- (2-succinimidyl-oxycarbonylethyl) phenyl-10-methylacridinium-9-carboxylate methosulfate (EP-A-Publication No. 82,636, page 10). 100 μΐ of each of the tracer solutions is stimulated by adding 350 μΐ 0.05 M KCl / NaOH buffer 10 pH 13 + 0.1% H2O2 to chemiluminescence and recorded over a period of 10 seconds.
I fig. 1 nås den maksimale lysemission allerede efter 0,66 sekunder, og den er allerede efter 0,88 sekunder igen faldet til halvdelen. I forhold hertil nås den maksimale 15 lysemission først efter 1,77 sekunder i fig. 2, og den falder først efter 2,88 sekunder igen til halvdelen.In FIG. 1, the maximum light emission is reached already after 0.66 seconds and it has already fallen to half again after 0.88 seconds. In this respect, the maximum light emission is only reached after 1.77 seconds in FIG. 2, and it only drops to half again after 2.88 seconds.
Det var fuldstændig uventet, at på amidnitrogenet sulfonylsubstituerede acridinium-9-carboxylsyreamider har en udmærket kemiluminescens, da det vides, at acridinium-20 9-carboxylsyreamid i modsætning til acridinium-9-carboxyl-syreestere ikke viser nogen kemiluminescens (jfr. F. McCapra i W. Carruthers og J.K. Sutherland; Progress in Organic Chem., vol. 8, 231-277, 1973, Butterworth, London).It was completely unexpected that the amide nitrogen sulfonyl-substituted acridinium-9-carboxylic acid amides have an excellent chemiluminescence, since it is known that, unlike acridinium-9-carboxylic acid esters, acridinium-9-carboxylic acid esters show no chemiluminescence F. in W. Carruthers and JK Sutherland; Progress in Organic Chem., Vol. 8, 231-277, 1973, Butterworth, London).
Acridinium-9-carboxylsyrethioestere ifølge opfindelsen 25 fremstilles ved den her omhandlede fremgangsmåde, som er ejendommelig ved det i de kendetegnende dele af kravene 7 og 8 angivne.Acridinium-9-carboxylic acid ethioesters of the invention 25 are prepared by the process of this invention, which is characterized by the features of claims 7 and 8.

Syrechloridet (VIII) omsættes derpå med en thiocarb-oxylsyre med den almene formel IX, 25 HS - X - COOH (IX) f.eks. med 2-mercaptobenzoesyre, under basiske betingelser til dannelse af en thiolestercarboxylsyre, der herefter forestres med en til dannelse af gruppen R5 egnet forbin-30 delse, f.eks. med N-hydroxysuccinimid. Herefter alkyleres acridinforbindelsen i 10-stillingen efter i litteraturen kendte fremgangsmåder. Egnet til en methylering er frem for alt trimethyloxoniumtetrafluorborat, men der kan dog også med dimethyl sul fat, methylfluorsulfonat, toluensul fonsy remethyl-35 ester eller trifluormethansulfonsyremethylester opnås gode udbytter af en kemiluminiserende acridiniumforbindelse.The acid chloride (VIII) is then reacted with a thiocarboxylic acid of the general formula IX, HS - X - COOH (IX) e.g. with 2-mercaptobenzoic acid, under basic conditions to form a thiol ester carboxylic acid, which is then esterified with a compound suitable for the group R5, e.g. with N-hydroxysuccinimide. Thereafter, the acridine compound is alkylated at the 10-position according to methods known in the literature. Suitable for methylation is primarily trimethyloxonium tetrafluoroborate, however, good yields of a chemiluminescent acridinium compound can also be obtained with dimethyl sulphate, methyl fluorosulphonate, toluene sulphonic remethyl ester or trifluoromethanesulphonic acid methyl ester.

F.eks. kan N-benzensulfonyl-glycinbenzylester anvendes ved denne reaktion som beskyttelsesgruppe. Den efter fraspaltning af beskyttelsesgruppen 25 fremkomne syre omdannes med en egnet forbindelse, f.eks. N-hydroxysuccinimid, til gruppen R5. Herfra udvindes den kemiluminescerende acridiniumforbindelse efter i litteraturen kendte fremgangsmåder ved alkylering på nitrogenet i 10--stillingen.R6 - N - SO2 - X - COOZ (XI) 20 where X and R *> have the above meanings and Z means a group protecting the carboxy group, which protecting group is eventually split off. For example. For example, N-benzenesulfonyl-glycine benzyl ester can be used as a protecting group. The acid obtained after cleavage of the protecting group 25 is converted with a suitable compound, e.g. N-hydroxysuccinimide, to the group R5. From this, the chemiluminescent acridinium compound is recovered according to methods known in the literature by alkylation on the nitrogen at the 10-position.
30 De fremkomne acridiniumforbindelser lader sig herefter omsætte med en substans af biologisk interesse, f.eks. et antigen, et antistof, et hormon, et lægemiddel, en læge-middelmetabolit, et toxin eller et alkaloid til en lumin-escerende forbindelse. Derved er acridiniumderivatet enten 35 direkte eller over et bromolekyle, såsom polylysin, poly-glutaminsyre eller polyvinylamin, bundet til den biologisk interessante substans under dannelse af et stabilt immunologisk aktivt konjugat. Dette konjugat betegnes også som en tracer, og det anvendes i de i det efterfølgende beskrevne 40 luminescensimmunanalyser. Til luminescens immunanalysen ifølge 11 DK 171437 B1 opfindelsen til bestemmelse af en antigen-substans i en væskeprøve efter en kompetitiv-eller en sandwich-fremgangsmåde er det nødvendigt med mindst én immunologisk aktiv komponent, der er immobiliseret på en fast fase og desuden 5 den luminescerende tracer.The resulting acridinium compounds can then be reacted with a substance of biological interest, e.g. an antigen, an antibody, a hormone, a drug, a drug metabolite, a toxin or an alkaloid for a luminescent compound. Thereby, the acridinium derivative, either directly or over a bromolecule such as polylysine, polyglutamic acid or polyvinylamine, is bonded to the biologically interesting substance to form a stable immunologically active conjugate. This conjugate is also referred to as a tracer and it is used in the 40 luminescence immunoassays described below. For the luminescence immunoassay of the invention to determine an antigenic substance in a liquid sample following a competitive or sandwich process, at least one immunologically active component immobilized on a solid phase is required and in addition the luminescent tracer.
Både den luminescerende forbindelse og luminescens-immunanalysen er genstand for patentkrav i DK-A nr. 0684/92.Both the luminescent compound and the luminescence immunoassay are subject to claims in DK-A No. 0684/92.
Luminescensimmunanalysen kan gennemføres på forskellige måder.The luminescence immunoassay can be performed in various ways.
10 En mulighed består i, at det med antigenet specifikt reagerende immobiliserede antistof inkuberes med en prøve af den væske, der skal undersøges, og et konjugat af antigenet og et kemiluminescerende acridiniumderivat (antigen-tracer) , hvorefter prøven og den ikke-bundne tracer skilles 15 fra, og den bundne tracer bringes sammen med et oxidationsmiddel for at fremkalde en lysemission, hvorefter man ud fra den målte styrke af lysemissionen bestemmer mængden af tilstedeværende antigen.One possibility is that the antigen specifically reacting immobilized antibody is incubated with a sample of the liquid to be tested and a conjugate of the antigen and a chemiluminescent acridinium derivative (antigen tracer), after which the sample and the unbound tracer are separated. 15, and the bound tracer is brought together with an oxidizing agent to induce a light emission, after which the amount of antigen present is determined from the measured strength of the light emission.
En anden mulighed for gennemførelse af luminescensim-20 munanalysen består i, at et med antigenet specifikt reagerende immobiliseret antistof inkuberes med en prøve af den væske, der skal undersøges, med et konjugat med et andet specifikt reagerende antistof og et kemiluminescerende acridiniumderivat, hvorefter prøven og det ikke-bundne mærkede 25 konjugat skilles fra, og det bundne mærkede konjugat bringes sammen med et oxidationsmiddel for at fremkalde en lysemission, hvorefter man ud fra den målte styrke af lysemissionen bestemmer mængden af tilstedeværende antigen.Another possibility for carrying out the luminescence immunoassay consists in incubating an antigen-specific reacting immobilized antibody with a sample of the liquid to be tested, with a conjugate with another specific reacting antibody, and a chemiluminescent acridinium derivative, and the unbound labeled 25 conjugate is separated, and the bound labeled conjugate is brought together with an oxidizing agent to induce a light emission, after which the amount of antigen present is determined from the measured strength of the light emission.
De ovenfor nævnte luminescensimmunanalyser kan også 30 gennemføres på den måde, at man skiller den væske, der skal undersøges, fra det immobiliserede antistof før tilsætningen af det mærkede konjugat.The above-mentioned luminescence immunoassays may also be performed by separating the liquid to be assayed from the immobilized antibody prior to the addition of the labeled conjugate.
I andre gennemførlige luminescensimmunanalyser ifølge opfindelsen er det ikke antistoffet men antigenet, der er 35 immobiliseret. Således kan et med antistoffet specifikt reagerende immobiliseret antigen inkuberes med en prøve af 12 DK 171437 B1 den væske, der skal undersøges, og en opløsning af et kon-jugat af antistoffet og et kemiluminescerende acridinium-derivat, hvorefter prøven og det ikke-bundne mærkede konjugat skilles fra, hvorefter det bundne mærkede konjugat bringes 5 sammen med et oxidationsmiddel. Der forekommer nu en lysemission, hvorefter man ud fra den målte styrke af lysemissionen bestemmer mængden af tilstedeværende antigen.In other feasible luminescence immunoassays of the invention, it is not the antibody but the antigen that is immobilized. Thus, an antibody specifically reacting immobilized antigen can be incubated with a sample of the liquid to be tested and a solution of a conjugate of the antibody and a chemiluminescent acridinium derivative, after which the sample and the unbound labeled the conjugate is separated and the bound labeled conjugate is brought together with an oxidizing agent. A light emission now occurs, after which the amount of antigen present is determined from the measured strength of the light emission.
En yderligere variant består i, at et med antistoffet specifikt reagerende immobiliseret antigen inkuberes med en 10 opløsning af et konjugat af antistoffet og et kemilumin-iscerende acridiniumderivat, hvorefter det ikke-omsatte mærkede konjugat skilles fra, og der tilsættes en prøve af den væske, der skal undersøges, hvorefter prøven igen skilles fra, og det bundne mærkede konjugat bringes sammen med et 15 oxidationsmiddel for at fremkalde en lysemission, og ud fra styrken af lysemissionen bestemmes mængden af tilstedeværende antigen.A further variant consists in incubating an antibody specifically reacting immobilized antigen with a solution of a conjugate of the antibody and a chemiluminescent acridinium derivative, then separating the unreacted labeled conjugate and adding a sample of the liquid. it is to be investigated, after which the sample is again separated and the bound labeled conjugate is brought together with an oxidizing agent to induce a light emission, and from the strength of the light emission the amount of antigen present is determined.
Endelig er luminescensimmunanalysen også gennemførlig på den måde, at et med antistoffet specifikt reagerende 20 immobiliseret antigen inkuberes med en opløsning af et konjugat af antistoffet og et kemiluminescerende acridiniumderivat, hvortil der sættes en prøve af den væske, der skal undersøges, og prøven og det ikke-bundne konjugat skilles fra, og det bundne mærkede konjugat bringes sammen med et 25 oxidationsmiddel for at fremkalde en lysemission, hvorefter man ud fra den målte styrke af lysemissionen bestemmer mængden af tilstedeværende antigen.Finally, the luminescence immunoassay is also feasible in that an antibody specifically reacting with the antibody is incubated with a solution of a conjugate of the antibody and a chemiluminescent acridinium derivative to which a sample of the liquid to be tested is added and the sample and the -bonded conjugate is separated and the bound labeled conjugate is brought together with an oxidizing agent to induce a light emission, after which the amount of antigen present is determined from the measured strength of the light emission.
