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 ) 用伊氏錐蟲云南水牛單克隆株yntat1感染兔，感染后30天內，每3天從兔血中分離錐蟲并單蟲克隆，最后一個未單蟲克隆的蟲株感染另一只兔，重復以上操作，這樣順序感染5只兔子，共獲得50個單克隆錐蟲種群( tp ) ，經間接免疫熒光和abc酶標試驗鑒定共為20個抗原性互不相同的抗原變異體( vats ) 。

Surface plasmon resonance immunosensor is a relatively new immunoassay technique and has been receiving more and more attention in recent years . however , a major disadvantage of spr for bioanalytical applications is that low concentration or low molecular mass analytes could not be detected directly . therefore , it is a challenging task to develop strategies for improving the detection limit sensitivity of spr . in this paper , authors present a novel strategy for improving the sensitivity of spr immunosensing using streptavidinbiotinylated antibody complex . it is proven that the amplification strategy causes a dramatic improvement of the detection sensitivity . this amplification strategy is based on the construction of a molecular complex between streptavidin and biotin labeled protein . the complex can be formed in a crosslinking network of molecules so that the amplification of response signal will be realized due to the big molecular size of complex 將鏈霉親和素-生物素系統用于表面等離子體共振免疫傳感的信號放大，實時檢測了人免疫球蛋白g higg的蛋白濃度。發生免疫反應的傳感片和生物素化抗體反應后，傳感片表面的一層生物素分子隨后與鏈霉親和素-生物素化抗體復合物中的鏈霉親和素的活性位點發生親和反應，從而使傳感片表面特異健合的物質質量顯著增加，大大提高了免疫檢測的靈敏度和檢測限。免疫反應經放大后，可檢測0 . 00510g ml濃度區間內的higg 。
