Description
Fremgangsmåte til utvinning av ren nukleinsyre. Method for extracting pure nucleic acid.
Foreliggende oppfinnelse angår en fremgangsmåte for fra animalske eller ve-getabilske råmaterialer, og spesielt fra kold fiskemelke, å utvinne ren nukleinsyre. The present invention relates to a method for extracting pure nucleic acid from animal or vegetable raw materials, and in particular from cold fish milk.
Det kjennes fremgangsmåter til behandling av forskjellige animalske stoffer for å utvinne nukleinsyre, særlig ved behandling av animalske materialer med natronlut og utfelling av nukleat med alkohol. Disse fremgangsmåter gir forurensede nuk-leinsyrer. Hvis man ønsker å få ren nukleinsyre, må man utsette materialet for en behandling for å befri det for de organiske og mineralske forurensninger, og utføre ekstrahering og utfelling først med tem-melig rene produkter. Tysk patent nr. 304.003 beskriver således en fremgangsmåte for rensning av hydrolyserte proteiner ifølge hvilken hydrolyseoppløsningene behandles med kalsium- eller magnesium-hydroksyd eller en blanding av disse for å eliminere visse forurensninger som gela-tinøse stoffer eller stoffer som med kalk eller magnesia danner uoppløselige salter. Selve proteinstoffene påvirkes ikke av denne behandling. Methods are known for treating various animal substances to extract nucleic acid, in particular by treating animal materials with caustic soda and precipitation of nucleate with alcohol. These methods give contaminated nucleic acids. If one wishes to obtain pure nucleic acid, one must subject the material to a treatment to rid it of organic and mineral contamination, and carry out extraction and precipitation first with relatively clean products. German patent no. 304,003 thus describes a method for the purification of hydrolysed proteins according to which the hydrolysis solutions are treated with calcium or magnesium hydroxide or a mixture of these to eliminate certain impurities such as gelatinous substances or substances which with lime or magnesia form insoluble salts . The protein substances themselves are not affected by this treatment.
Fremgangsmåten etter oppfinnelsen, The method according to the invention,
hvor ren nukleinsyre utvinnes fra de nevnte råstoffer, og hvor råstoffer, f. eks. på forhånd opphakket fersk fiskemelke behandles med alkalilut og alkalinukleat felles ut med alkohol, karakterisert ved at det utfelte alkalinukleat renses ved behandling under oppvarmning med kalsiumsulfat i nærvær av vann og ved at det fra den rensede oppløsning av alkalinukleat felles ut praktisk talt ren nukleinsyre ved hjelp av en blanding av alkohol og saltsyre, hvor- where pure nucleic acid is extracted from the aforementioned raw materials, and where raw materials, e.g. previously chopped fresh fish milk is treated with alkali lye and alkali nucleate is precipitated with alcohol, characterized in that the precipitated alkali nucleate is purified by treatment while heating with calcium sulfate in the presence of water and that practically pure nucleic acid is precipitated from the purified solution of alkali nucleate using of a mixture of alcohol and hydrochloric acid, where-
etter, om ønsket, den erholdte nukleinsyre i alkoholisk suspensjon behandles med en alkoholisk oppløsning av natrium eller av et metallsalt for å danne ved dobbelt omsetning det tilsvarende nukleat. after, if desired, the obtained nucleic acid in alcoholic suspension is treated with an alcoholic solution of sodium or of a metal salt to form by double reaction the corresponding nucleate.
For å utføre fremgangsmåten ifølge foreliggende oppfinnelse må fersk fiskemelke opphakkes slik at det dannes en flytende velling. Denne velling behandles med konsentrert, varm alkalilut. Blandingen blir langsomt flytende, og hydrolysen stop-per når det hele danner en farget væske. In order to carry out the method according to the present invention, fresh fish milk must be chopped up so that a liquid gruel is formed. This gruel is treated with concentrated, hot alkaline lye. The mixture slowly becomes liquid, and the hydrolysis stops when the whole thing forms a colored liquid.
Det avkjøles til ca. 40°, og rå alkalinukleat utfelles med alkohol, det vaskes ved dekantering, og nukleatet fraskilles ved hjelp av kjente fysikalske metoder, f. eks. ved sentrifugering eller filtrering under trykk. It cools to approx. 40°, and crude alkali nucleate is precipitated with alcohol, it is washed by decantation, and the nucleate is separated by means of known physical methods, e.g. by centrifugation or filtration under pressure.
Den ikke tørkede utfelling renses ved innvirkning av kalsiumsulfat under oppvarmning i nærvær av vann. En første filtrering utført i varm tilstand for å hin-dre tilstopping av filtrene etterfølges av en annen filtrering av saften i kold tilstand for å fjerne alt av proteiner som er holdt tilbake av alkalinukleatet. Det fåes en klar, lett farvet oppløsning, som inneholder alkalinukleatet i praktisk talt ren tilstand. The undried precipitate is purified by the action of calcium sulfate during heating in the presence of water. A first filtration carried out in a hot state to prevent clogging of the filters is followed by a second filtration of the juice in a cold state to remove all proteins retained by the alkali nucleate. A clear, slightly colored solution is obtained, which contains the alkali nucleate in a practically pure state.
Nukleinsyre utfelles fra denne rensede oppløsning på hvilken som helst kjent måte, f. eks. ved hjelp av saltsur alkohol. Den fraskilles ved væskeatskillelse eller sentrifugering og vaskes med alkohol og aceton. Der fåes en praktisk talt ren tymonukleinsyre eller desoksyribonukleinsyre. Nucleic acid is precipitated from this purified solution in any known manner, e.g. using hydrochloric acid alcohol. It is separated by liquid separation or centrifugation and washed with alcohol and acetone. A practically pure thymonucleic acid or deoxyribonucleic acid is obtained.
For å fremstille salter av nukleinsyre tilsettes til en suspensjon av nukleinsyre i alkohol en alkoholisk oppløsning av natrium eller av et salt av det metall som skal danne nukleatet. Egnede salter er angitt under avsnitt II senere i denne be-skrivelse/ Metallnukleatet dannes ved dobbelt omsetning og kan fraskilles ved hvilken som helst kjent metode. To prepare salts of nucleic acid, an alcoholic solution of sodium or of a salt of the metal that is to form the nucleate is added to a suspension of nucleic acid in alcohol. Suitable salts are indicated under section II later in this description/ The metal nucleate is formed by double reaction and can be separated by any known method.
Eksempel. Example.
500 kg fersk fiskemelke hakkes opp inn-til der fåes en flytende velling. Denne velling behandles med 85 liter natronlut ved 36° Bé i en time ved 80° C. Det røres om under oppvarmningen. Den seige masse som til å begynne med dannes ved opp-tagelsen av natrium blir langsomt flytende, og der dannes etter en time en brunaktig væske som kjøles til 40° C. 500 kg of fresh fish milk is chopped up until a liquid gruel is obtained. This gruel is treated with 85 liters of caustic soda at 36° B for one hour at 80° C. It is stirred during the heating. The tough mass which is initially formed by the absorption of sodium slowly liquefies, and after an hour a brownish liquid is formed which cools to 40°C.
Hydrolysevæsken helles så i 650 liter alkohol av 80° G.L. Urent natriumnukleat felles ut og avsettes hurtig Væsken dekan-teres, og etter å ha vasket utfellingen tre ganger med alkohol ved 80° G.L. samles utfellingen opp etter å ha atskilt væsken i størst mulig utstrekning. The hydrolysis liquid is then poured into 650 liters of alcohol of 80° G.L. Impure sodium nucleate precipitates out and settles quickly. The liquid is decanted, and after washing the precipitate three times with alcohol at 80° G.L. the precipitate is collected after having separated the liquid to the greatest possible extent.
Utfellingen som er befridd for væske men ikke tørket, blandes med en pasta dannet av 97 liter vann og 5.25 kg kalsiumsulfat for 75 kg av utfellingen. Det blandes energisk og opphetes til 80° C. Blandingen filtreres i varm tilstand, filtratet avkjøles og filtreres påny. Det fåes mellom 85 og 90 liter av en klar, gylden saft. 8 volumdeler av denne saft helles i en lunken blanding av 16 volumdeler alkohol av 75/80° G.L. og 1.8 volumdeler saltsyre. Etter energisk omrøring avsetter nukleinsyre seg i form av et hvitt bunnfall. Dette oppsamles, vaskes med alkohol ved dekantering, væsken skilles fra eller den sentri-fugeres og det vaskes påny tre ganger med alkohol og en gang med aceton. The precipitate, which is freed from liquid but not dried, is mixed with a paste formed from 97 liters of water and 5.25 kg of calcium sulfate for 75 kg of the precipitate. It is mixed vigorously and heated to 80° C. The mixture is filtered while hot, the filtrate is cooled and filtered again. Between 85 and 90 liters of a clear, golden juice is obtained. 8 parts by volume of this juice are poured into a lukewarm mixture of 16 parts by volume of alcohol of 75/80° G.L. and 1.8 parts by volume of hydrochloric acid. After vigorous stirring, nucleic acid settles in the form of a white precipitate. This is collected, washed with alcohol by decantation, the liquid is separated or it is centrifuged and it is washed again three times with alcohol and once with acetone.
Der fåes et hvitt, lett og meget fint pulver av tymonukleinsyre som inneholder omtrent: A white, light and very fine powder of thymonucleic acid is obtained which contains approximately:
Denne syre gir med natriumacetat en stabil oppløsning som ikke inneholder organiske eller mineralske stoffer. II. En del av tymonukleinsyre utvun-net i eksempel 1 utrøres med alkohol av 85° G.L. Det tilsettes en alkoholisk oppløs-ning av natrium, eller av sulfater av mangan, kopper, jern, kalsium-, magnesium-eller koboltklorid etc. for å få de tilsvarende tymonukleater av natrium, mangan, kopper, jern, magnesium, kobolt etc. som dannes ved dobbelt omsetning. With sodium acetate, this acid gives a stable solution that does not contain organic or mineral substances. II. A portion of thymonucleic acid extracted in example 1 is stirred with alcohol of 85° G.L. An alcoholic solution of sodium, or of sulphates of manganese, copper, iron, calcium, magnesium or cobalt chloride etc. is added to obtain the corresponding thymonucleates of sodium, manganese, copper, iron, magnesium, cobalt etc. which formed by double turnover.
