WebOur Complement C5a polyclonal, monoclonal and recombinant monoclonal antibodies are developed in Rabbit, Mouse, Goat, Rat and Sheep. These antibodies have been verified by Neutralization to confirm specificity to Complement C5a. Find the Complement C5a antibody that fits your needs. C5a is an anaphylatoxin, causing increased expression of adhesion molecules on endothelium, contraction of smooth muscle, and increased vascular permeability. C5a des-Arg is a much less potent anaphylatoxin. Both C5a and C5a des-Arg can trigger mast cell degranulation, releasing proinflammatory molecules histamine and TNF-α. C5a is also an effective chemoattractant, initiating accumulation of complement and phagocytic cells at sites of infection or recruitment of antigen-…
