特異性:Recognizes the human serum complement protein factor H (155kD), binding to a different epitope from MRC OX23. The Recognizes a 43-49kD truncated form of factor H present at low level (1-5 ug/ml) in plasma and urine. In an immunoprecipitation system. Recognizes factor H in other primates, but not in cow, sheep, pig, chicken or rabbit sera. This antibody inhibits the binding of factor H to surface bound C3b, Recognizes Factor H in Western blotting procedures.
