Den fibrinolytiske virkning av kulturfiltrater av The fibrinolytic action of culture filtrates of
mange streptokokkstammer er kjent. Som stoff som er ansvarlig for dette ble det oppdaget streptokinase. Det dannes ved siden av mange andre stoffer som f.eks. streptodornase, streptolysin eller hyaluronidase under bestemte kulturbetingelser. For en terapeutisk anvendelse er det derfor ubetinget nødvendig en ad- many streptococcal strains are known. Streptokinase was discovered as the substance responsible for this. It is formed next to many other substances such as e.g. streptodornase, streptolysin or hyaluronidase under specific culture conditions. For a therapeutic application it is therefore absolutely necessary an ad-

En av de herved opptredende hovedvanskeligheter ligger One of the main difficulties arising in this way lies
i håndteringen av de derved dannede relativt store væskemengder, in the handling of the resulting relatively large amounts of liquid,
forbundet med relativt små streptokinasemengder. De tidligere metoder anvender til konsentrering utfellingsreaksjoner med etanol, metanol, ammoniumsulfat eller andre oppløsningsmidler. Ulempen ved disse metoder består på den ene side i ofte ikke meget høye utbytter, i forbruk av store mengder tilsetningsstoffer, forbundet med en primær volumøkning og i relativt liten rensefaktor. associated with relatively small amounts of streptokinase. The previous methods use precipitation reactions with ethanol, methanol, ammonium sulphate or other solvents for concentration. The disadvantage of these methods consists, on the one hand, in often not very high yields, in the consumption of large amounts of additives, associated with a primary volume increase and in a relatively small purification factor.
Videre er det kjent en fremgangsmåte til rensing av streptokinase, idet denne fremgangsmåte er karakterisert ved at man adsorberer en fra streptokokkfiltratet utvunnet streptokinase- Furthermore, a method for purifying streptokinase is known, as this method is characterized by adsorbing a streptokinase extracted from the streptococcal filtrate
holdig vandig pufferoppløsning med molaritet på 0,01 med en pH- containing aqueous buffer solution with a molarity of 0.01 with a pH
verdi på 5,0 på karboksymetylpolysakkarid, utvasker med puffer-oppløsning av samme molaritet og eluerer hovedfraksjonen av streptokinase med 0,2 molar pufferoppløsning av pH-verdi 5,5. value of 5.0 on carboxymethyl polysaccharide, wash out with buffer solution of the same molarity and elute the main fraction of streptokinase with 0.2 molar buffer solution of pH value 5.5.
Fra norsk patent 113.095 er det på den annen side From Norwegian patent 113,095 it is on the other side
kjent en fremgangsmåte til rensing av rå streptokinase, idet denne known a method for the purification of crude streptokinase, as this
fremgangsmåte er karakterisert ved at streptokinase adsorberes ved molare fosfatpufferkonsentrasjoner fra 0,005 til 0,015 på celluloseioneutvekslerharpiks og deretter eluerer forurensninger ved gradienteluering ved hjelp av fosfatpuffere i første rekke ved en molarkonsentrasjon fra 0,02 til 0,06 og deretter elueres streptokinase ved molare konsentrasjoner fra 0,06 til 0,15. method is characterized in that streptokinase is adsorbed at molar phosphate buffer concentrations from 0.005 to 0.015 on cellulose ion exchange resin and then contaminants are eluted by gradient elution using phosphate buffers in the first place at a molar concentration from 0.02 to 0.06 and then streptokinase is eluted at molar concentrations from 0, 06 to 0.15.
Denne fremgangsmåte gjennomføres hele tiden ved pH 7,5. This procedure is carried out all the time at pH 7.5.
En tilsvarende fremgangsmåte er også kjent fra US-patent 344404-5, idet det likeledes er omtalt en finrensing av rå streptokinase ved behandling med DEAE-cellulose. Streptokinase elueres deretter fra cellulosen med 0,1 til 0,15 molar fosfat-puf f er . A similar method is also known from US patent 344404-5, as a fine purification of crude streptokinase by treatment with DEAE cellulose is also described. Streptokinase is then eluted from the cellulose with 0.1 to 0.15 molar phosphate buffer.
Den foreliggende oppfinnelse har til formål å tilveie-bringe en fremgangsmåte til utvinning av streptokinase fra kulturfiltrater av streptokokker, som forbinder høye utbytter, lite materialforbruk og en høy rensningseffekt. The purpose of the present invention is to provide a method for extracting streptokinase from culture filtrates of streptococci, which combines high yields, low material consumption and a high purification effect.
Oppfinnelsen vedrører en fremgangsmåte til utvinning av streptokinase fra kulturfiltrater av streptokokker, hvor streptokinasen utfelles på et adsorberende materiale ved pH-verdier under 3,5 og etter fjerning av forurensninger ved vask elueres med en pufferoppløsning med alkalisk pH-verdi, hvoretter streptokinasen utvinnes fra eluatet, idet fremgangsmåten er karakterisert ved at det som adsorberende materiale anvendes karboksymetylcellulose og forurensninger fjernes ved vask med fortynnet iseddik. The invention relates to a method for the recovery of streptokinase from culture filtrates of streptococci, where the streptokinase is precipitated on an adsorbent material at pH values below 3.5 and after removal of impurities by washing is eluted with a buffer solution with an alkaline pH value, after which the streptokinase is recovered from the eluate , the method being characterized in that carboxymethyl cellulose is used as adsorbent material and contaminants are removed by washing with diluted glacial acetic acid.

lar CM-cellulosen seg adskille lett med den bundne streptokinase. Ved utvasking av CM-cellulosen med 0,01 N eddiksyre lar de fleste medrevne næringsbestanddeler seg fjerne. Streptokinasen gjen-vinnes ved eluering med 0,05 molar fosfatpuffer, som er 0,1 molar med hensyn på natriumklorid, ved pH=8,0. I eluatet kan streptolysinet etter kjente fremgangsmåter ved tilsetning av CaC^ fjernes på det kalsiumfosfat som danner seg, idet samtidig den største del av forurensninger fjernes. Det således dannede produkt utfelles enten med etanol eller ammoniumsulfat på kjent måte, dialyseres mot vann og lyofiliseres. Det inneholder ca. 30.000 _Christensen-enh.eter pr. mg protein og er fritt for streptolysin. allows the CM-cellulose to dissociate easily with the bound streptokinase. By washing out the CM cellulose with 0.01 N acetic acid, most entrained nutrients can be removed. The streptokinase is recovered by elution with 0.05 molar phosphate buffer, which is 0.1 molar with respect to sodium chloride, at pH=8.0. In the eluate, the streptolysin can be removed by known methods by adding CaC^ on the calcium phosphate that forms, while at the same time the largest part of impurities is removed. The product thus formed is precipitated either with ethanol or ammonium sulfate in a known manner, dialyzed against water and lyophilized. It contains approx. 30,000 _Christensen units per mg protein and is free of streptolysin.
Som næringssubstrat for dyrking av streptokokkene tjener tryptisk kaseinpepton med glukose, salt- og vitamintil-setninger. Andre næringsbunner gir dårligere utbytter. Tryptic casein peptone with glucose, salt and vitamin additives serves as a nutrient substrate for growing the streptococci. Other nutrients give poorer yields.
Det kreves fortrinnsvis ingen dyre tilsetningsstoffer, Preferably no expensive additives are required,
den praktiske utførelse er enkel, den anvendte CM-cellulose er regenererbar, utbyttene svinger mellom 60 og 90% og det ekstra- the practical implementation is simple, the CM cellulose used is renewable, the yields fluctuate between 60 and 90% and the extra-
herte kulturfiltrat er praktisk talt sterilt og kan kasseres uten ytterligere behandling. Ved felling av streptokinase på en ione-utveksler kan det videre ved bestemte ekstraheringsbetingelser fjernes hovedmengden av forurensninger uten ekstra arbeids<p>rosess. hardened culture filtrate is practically sterile and can be discarded without further treatment. By precipitating streptokinase on an ion exchanger, the main amount of contaminants can be removed without additional work under specific extraction conditions.
Oppfinnelsen skal forklares nærmere ved hjelp av et The invention shall be explained in more detail by means of a
eksempel: Example:
10 g CM-cellulose ekvilibreres med 500 ml 0,2 N 10 g of CM cellulose is equilibrated with 500 ml of 0.2 N
eddiksyre i 30 minutter og vaskes deretter med 500 ml 0,01 N acetic acid for 30 minutes and then washed with 500 ml of 0.01 N
eddiksyre. Den således forberedte karboksymetylcellulose setter man til 5 liter streptokokk-kulturfiltrat, hvis pH-verdi på for- acetic acid. The carboxymethylcellulose prepared in this way is added to 5 liters of streptococcus culture filtrate, whose pH value of
hånd ble innstilt til 3,0. Etter to timers omrøring filtrerer man over en grov glassfritte (G2) og kasserer filtratet. CM-cellulo- hand was set to 3.0. After stirring for two hours, filter over a coarse glass frit (G2) and discard the filtrate. CM Cellulose
sen vaskes med 0,5 1 0,01 N eddiksyre. Deretter eluerer man streptokinasen med 1 liter fosfatpuffer (0,05 molar fosfat, 0,1 then wash with 0.5 1 0.01 N acetic acid. The streptokinase is then eluted with 1 liter of phosphate buffer (0.05 molar phosphate, 0.1
molar NaCl, pH=8,0). pH-verdien i eluatet ble innstilt til 7,0 molar NaCl, pH=8.0). The pH value in the eluate was adjusted to 7.0
og streptolysinet utfelt med 10 ml 1 molar CaCl2 ved konstant holdt pH-verdi. Utfellingen ble bortsentrifugert etter 30 minutter og kassert. Streptokinasen felles ved pH 5,5 med 350 g ammonium- and the streptolysin precipitated with 10 ml of 1 molar CaCl2 at a constant pH value. The precipitate was centrifuged off after 30 minutes and discarded. The streptokinase is combined at pH 5.5 with 350 g of ammonium
sulfat (pr. liter). Den dannede utfelling oppløser man i ca. sulphate (per litre). The formed precipitate is dissolved in approx.
60 ml vann, innstiller suspensjonens pH-verdi til 9,0, dialyserer sulfatfri og lyofiliserer. 60 ml of water, adjust the pH value of the suspension to 9.0, dialyze sulfate-free and lyophilize.
Man får 450 mg streptokinase med en titer på 2,5x10<4 >Christensen-enheter pr. mg. Det tilsvarer 80% av utgangsaktivi-teten. For terapeutiske formål kan det dannede produkt videre- You get 450 mg of streptokinase with a titer of 2.5x10<4 >Christensen units per mg. This corresponds to 80% of the output activity. For therapeutic purposes, the product formed can further
