生物素(Biotin、B)与抗生物素蛋白(A-vidin、A)有极强的亲和力。70年代后期利用这一特性建立起来的BA系统(BAS)是一种新型的生物反应放大系统,已广泛用于抗原、抗体、多肽物质的检测以及细胞受体、基因的组织化学染色定位研究上,被认为是一种灵敏度很高,具有广阔发展前景的新的检测系统。我们在研制成功BAS的基础
Biotin, B has a strong affinity with A-vidin (A). The BA system (BAS) established by this characteristic in the late 1970s is a new type of biological reaction amplification system. It has been widely used in the detection of antigens, antibodies and peptides, as well as cellular receptors and histochemical staining of genes , Is considered as a new detection system with high sensitivity and broad development prospects. We are in the successful development of BAS basis
