S-2266,Chromogenic Substrates for Kallikrein


Kallikrein chromogenic substrate S-2266 is a short peptide covalently bound to pNA (4-nitroaniline). A free pNA will be cleaved off the peptide chain by Kallikrein, thus enabling quantitive detection by a spectrophotometer.

Asnail provides S-2266 for Kallikrein activity assay of coagulants.
