DiaPharma CS – GK is a chromogenic peptide substrate for glandular kallikrein (GK). DiaPharma CS – GK may be used for kallikrein activity determination in purified preparations, urine, and saliva. A urine kallikrein activity research method using substrate H-D-Val-Leu-Arg-pNA is available.
Each vial contains chromogenic substrate H-D-Val-Leu-Arg-pNA · 2HCl 25 mg and mannitol 60 mg added as a bulking agent.
H-D-Val-Leu-Arg-pNA · 2HCl
H-D-Val-Leu-Arg-pNA + Enzyme è H-D-Val-Leu-Arg-OH + pNA
H-D-Val-Leu-Arg-pNA + Enzyme → H-D-Val-Leu-Arg-OH + pNA
