CAS Number: 86030-63-9 Molecular Weight: 1259.68 Salt Form: TFA Purity: >96% Sequence (3-letter): Ile-Ser-Arg-Pro-Pro-Gly-Phe-Ser-Pro-Phe-Arg-OH Sequence (1-letter): ISRPPGFSPFR-OH Storage: -20 ?C or below Bradykinin is a potent vasodilator peptide that exerts its action through stimulation of specific endothelial receptors. It has been linked with the pathophysiological process that accompanies tissue damage and inflammation. T-kinin (Ile-Ser Bradykinin)is found in rat plasma as a product of T-kininogen. It has similar but not identical activity as bradykinin.
