METHOD FOR PREPARING CARRIER OF ANTIGENS BASED ON LIPIDS FROM SEA MACROPHYTES AND TRITERPENE GLYCOSIDE CUCUMARIOSIDE

摘要

FIELD: biotechnology. ^ SUBSTANCE: invention relates to carriers of antigens. Proposed carrier represents lipid-saponin complex consisting of a mixture of triterpene glycoside, cholesterol and glyceroglycolipid. Cucumarioside A2-2 is used as triterpene glycosides, and monogalacosyldiacylglycerides of sea macrophites are used as glyceroglycolipids. Method involves mixing solutions of cholesterol and glyceroglycolipid in chloroform, evaporation of mixture until dry under vacuum, addition of 3 weight parts of 0.4% aqueous solution of cucumarioside. Then the mixture is solubilized and the total concentration of cholesterol and glyceroglycolipid is brought about to 2 mg in 1 ml of suspension with phosphate-saline buffer at pH 7.2 followed by sonication of the prepared suspension by ultrasonic oscillation device at frequency 20 kHz for 5 min. Method provides preparing the effective adjuvant form of the carrier. ^ EFFECT: improved preparing method of carrier. ^ 6 cl, 8 dwg, 13 ex
