摘要
新城疫病毒(NDV)鸡胚尿囊液和产蛋下降综合症病毒(EDSV)鸭胚尿囊液在不同保护剂和保存条件下血凝(HA)试验结果表明,以10%甘油做保护剂制备的抗原,在-18℃、4~8℃和常温条件下可保存一年,其HA效价稳定。抗原制备方法简单,成本低廉,适合基层生产单位使用。
Hemagglutination test of NDV chicken embryo and EDSV duck embryo allantoic fluid under different protective conditions showed that the prepared antigen using 10% glycerol as protective agent can be kept for one year under -18℃,4~8℃,and common temperature conditions,with HA titer having no significant change.This method preparing HI antigen is simple,with low cost and wide spreading value.
