Description: C5a des Arg, Human, Recombinant

Complement fragment C5a is a 74-residu glycopolypeptide which is generated by proteolytic cleavage of the complement factor C5 in the course of complement activation. C5a is a potent chemoattractant and anaphylatoxin that acts on all classes of leukocytes and on many other cell types including endothelial, smooth muscle, kidney, liver, and neural cells. In addition to its proinflammatory effects, C5a has been shown to protect cells against toxic insult and to stimulate proliferation in neurons and hepatocytes, suggesting a wider role for C5a in homeostasis. C5a is rapidly desarginated by serum carboxypeptidase N to the less potent derivate C5a desArg, the first stage in deactivation of anaphylatoxin activity. The C5a desArg form has a different spectrum of bioactivity to intact C5a. Recombinant Human C5a desArg is His-tagged and has the following amino acid sequence: MRGSHHHHHHGSDYDIPTTENLYFQGGSTLQKKIEEIAAKYKHSVVKKCCYDGACVNNDETCEQRAARISLGPRCIKAFTECCVVASQLRANISHKDMQLG ((His-tag is underlined, bold sequence is tevprotease)

Lyophilized product in 0.005% Tween 80, 2mM reduced L-glutathion, 0.2mM oxidized L-glutathion and 0.1M Tris-Cl buffer, pH 8.0, containing at least 50 μg human C5a desArg. The exact amount is indicated on the label. Reconstitute the vial by pipetting 0.5 ml distilled or de-ionised water (Caution: vial is under vacuum).

For dilutions use protein stabilized phosphate buffered saline, pH 7.4.

Lyophilized product should be stored at 4°C. Store stock solution after reconstitution in aliquots at -20°C. Repeated freeze and thaw cycles cause loss of activity. Under recommended storage conditions, product is stable for one year.
