It increases the detectable rate of antigen and sensitivity by applying biotin - avidin system to p24 antigen detection system 将生物素-亲和素系统应用到p24抗原检测系统，提高了抗原检出率和假阳性。

A rabbit was infected with a cloned yntatl , blood was collecting from from the rabbit every 3 days after infection within 30 days , 10 clonal trypanosome populations were gotten , infecting a new rabbit by the last non - cloned trypanosome population . repeated above all , thus infected 5 rabbits sequentially . twenty different vats ( variant antigen type ) were monitored and characterized from those fifty mono - clonal populations by indirect immunofluorescence test ( ift ) and avidin biotin enzyme immunoassay ( abc - eia ) 用伊氏锥虫云南水牛单克隆株yntat1感染兔，感染后30天内，每3天从兔血中分离锥虫并单虫克隆，最后一个未单虫克隆的虫株感染另一只兔，重复以上操作，这样顺序感染5只兔子，共获得50个单克隆锥虫种群( tp ) ，经间接免疫荧光和abc酶标试验鉴定共为20个抗原性互不相同的抗原变异体( vats ) 。
