Product Information
| Description: | Compstatinis is a 13-residue cyclic peptide, binds to complement component C3 and inhibits complement activation with IC50 of 12 μM. Compstatin exhibits exclusive specificity for primate C3s and does not bind either to C3s from lower mammalian species or to two structural homologs of C3, human C4 and C5. |
| Stability and Solubility Advice: | Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide. We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials and used within 1 month. Avoid repeated freeze and thaw cycles. Storage conditions for some special products should refer to their storage details. |
