產品描述
Highly purified human Victronectin was isolated and used to immunize rabbits. The Anti-Human Vitronectin
polyclonal antisera was tested by immunodiffusion methods and determined to be monospecific for the Vitronectin
protein
背景
In contrast to membrane-formed C5b-9 complexes, C5b-9 complexes formed in the fluid phase contain an
additional protein, the S protein. Subsequently, it was found that isolated S protein inhibited C5b-9 attachment. S
protein functions like a “membrane analogue” in that it binds to the binding site generated on assembly of C5b-9
and is required for insertion of the complex into the membrane. As a result, SC5b-7, SC5b-8 or SC5b-9 complexes
are formed which have lost their membrane-binding capacity. When the S protein was cloned and sequenced, it
was found to be identical to Vitronectin. Within the complement cascade, Vitronectin not only inhibits attachment
of C5b-9 to target cells, but also prevents C9 polymerization. The biological function of Vitronectin is to minimize
complement-mediated attack of cells near an ongoing complement attack
應用
Applications of the Anti-Human Vitronectin antisera have been evaluated, and include immunodiffusion, Western
Blot and ELISA
