Details:

(TRP63,TRP64)-C3A (63-77), 1mg This synthetic superagonist analogue of C3a exhibited the greatest biological potency of all peptides tested. It was 12-15 times more active than natural C3a. Such an optimal potency was obtained by introducing a bulky hydrophobic group such as Trp-Trp which binds more strongly to the hydrophobic site on the receptor than does the corresponding site on the natural ligand.
