Human C5a Protein, Recombinant - 50 µg (CAT#: CB-P287-AB) Datasheet

Product Type
Complement fragment C5a is a 74-residue glycopeptide that is produced by proteolytic cleavage of complement factor C5 during complement activation. C5a is an effective chemoattractant and anaphylactic toxin, acting on all types of white blood cells and many others. Cell types, including endothelial cells, smooth muscle, kidney, liver and nerve cells, in addition to pro-inflammatory effects, C5a can also protect cells from toxic damage and stimulate the proliferation of neurons and hepatocytes, which indicates that C5a is in homeostasis The role of C5a is more extensive. Serum carboxypeptidase N is deaminated to weaker derivative C5a desArg, which is the first stage of inactivation of anaphylactoxin activity. C5a desArg form has different biological activities from intact C5a. Recombinant human C5a has His -Tagged tag, and has the following amino acid sequence: MRGSHHHHHHHGSDYDIPTTENLYFQGGSTLQKKIEEIAAKYKHSVVKKCCYDGACVNNDETCEQRAARISL​​GPRCIKAFTECCVVA
