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-生物素系統用於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 。 -
