Treatment of human group C and G streptococci with cyanogen bromide results in solubilization of surface protein G molecules. Strain-to-strain variation in the quantity, molar mass and functional activity of protein G extracted from representative group C and G isolates led to the identification of three structurally and functionally distinct forms of the protein. Using different molecular biological approaches it was possible to determine the group of streptococci (C or G), or the quantity of IgG and HSA domains.
用溴化氰处理人C群和G群链球菌会导致表面蛋白G分子溶解。从代表性的C群和G群分离株中提取的蛋白G在数量、摩尔质量和功能活性方面存在菌株间差异，这导致鉴定出该蛋白的三种结构和功能不同的形式。使用不同的分子生物学方法可以确定链球菌群（C或G），或IgG和HSA结构域的数量。
