Description: Peptide to [Trp63, 64]-C3a (63-77) Form: Lyophilized powder CAS Number : 130154-64-2Molecular Formula : C86H134N26O18Molecular Weight : 1820.19Purity : > 95%Chemical Structure : Trp-Trp-Gly-Lys-Lys-Tyr-Arg-Ala-Ser-Lys-Leu-Gly-Leu-Ala-ArgApplication : [Trp63, 64]-C3a (63-77), synthetic superagonist analog of complement 3a, exhibited the greatest biological potency of all peptides tested. The peptide 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.Storage/Stability : Shipped at 4°C.
