Anti-Staphylococcus aureus clfA/Clumping factor A Reference Antibody|抗金黄色葡萄球菌clfA/凝集因子A参照抗体(靶标：金黄色葡萄球菌凝集因子A(研究用))

Clumping factor A (clfA) is a ~97 kDa protein. Cell surface-associated protein implicated in virulence. Promotes bacterial attachment exclusively to the gamma-chain of human fibrinogen. Induces formation of bacterial clumps, which diminish the ability of group IIA phospholipase A2 to cause bacterial phospholipid hydrolysis and killing. Significantly decreases macrophage phagocytosis possibly thanks to the clumps, clumped bacteria being too large to be phagocytosed. Dominant factor responsible for human platelet aggregation, which may be an important mechanism for initiating infective endocarditis.
