Anti-Complement component C3a/C3a (desArg) (human)
Mouse monoclonal antibody
Cat.No. GAU 017-01
Preparation: Protein-A/G purified
Content: Available in 200 µL and 1 mL size.1 mg/mL +/- 15%. See Certificate of Analysis for details.
Solvent: 0.01 M phosphate buffer, pH 7.4, with 0.5 M NaCl and 15 mM sodium azide
Storage: 4-8ºC without exposure to light. No precautions necessary during handling.
Complement C3a is an anaphylatoxin of 77 amino acid residues released by the action of the C3 convertases on the N-terminal of the alpha chain of C3. It is rapidly inactivated by serum carboxypeptidase N which removes the C-terminal arginine residue generating C3a (desArg).
Human C3a (1, 2)
Recognizes an epitope that is present on human C3, C3a and C3a (desArg) (2, 3).
Does not cross-react with C4a or C5a (2, 3).
GAU 017-01 recognizes different epitopes on the 9 kDa C3a than GAU 013-16 (2, 3). No reaction is seen with a synthetic octapeptide representing the C3a C-terminal (2).
GAU 017-01 can be used as a biotinylated detection antibody in sandwich ELISA with GAU 013-16 capture antibody. Does not inhibit the biological activity of C3a (4).
