Abstract

The invention provides an oil adjuvant containing panaxoside and a preparation method thereof. The oil adjuvant is a mixture consisting of panaxoside, adjuvant oil, aluminium stearate and sorbitol mono-oleic acid ester, wherein per milliliter of the oil adjuvant contains 10-100Mug of panaxoside. The preparation method comprises the following steps: heating the oil for preparing the adjuvant to thetemperature of 60-150 DEG C, adding 10-20milligram of aluminium stearate into per milliliter of oil, and mixing evenly; after the temperature of the oil reduces to 50-20 DEG C, adding 5-7% of dehydro-sorbitol mono-oleic acid ester according to volume ratio, stirring evenly, and filtering for standby; and using dimethyl sulfoxide or tween solvent to dissolve the panaxoside into solution; adding 10-100Mug of panaxoside solution into the per milliliter of the prepared standby matter, mixing evenly, and sterilizing for 30min at the temperature of 110 DEG C. Vaccines for immune animals, which is prepared by using oil containing panaxoside as the adjuvant, greatly improve the strength of specificity cells induced by the vaccines and humoral immune response, and reduce local stimulation reactionof injection sites.

Description

technical field [0001] The invention belongs to the field of biotechnology, and relates to a new vaccine adjuvant and a preparation method thereof, in particular to an oil adjuvant containing ginsenoside and a preparation method thereof. Using the adjuvant to prepare vaccines can greatly improve the specificity of vaccine induction. Intensity of sexual immune response and reduction of local irritation at the injection site. Background technique [0002] China is the world's largest breeding country, with a huge number of livestock and poultry, and nearly 900 million pigs, beef cattle, and sheep are slaughtered every year. There are many kinds of animal diseases, and after the scale of large-scale breeding is improved, the diseases are more likely to spread, so the task of animal disease prevention and control is very arduous. Compulsory immunization of livestock and poultry with vaccines is one of the important measures for disease prevention and control. Taking the foot-a...
