Kallikrein assay kit

iD Sensolyte® Assay Kits


Human plasma kallikrein, a serine protease, is first synthesized as an inactive plasma prekallikrein in liver and circulates in the plasma. Once activated by activated coagulation factor XII (FXIIa), plasma kallikrein releases bradykinin (an inflammatory mediator) from high molecular weight kininogen (HMWK). Plasma kallikrein is involved in several physiological and pathological processes such as blood coagulation, the classical complement cascade pathway and the activation of the alternative complement pathway.1, 2-5 Plasma kallikrein also plays a role in the induction of elastase release from neutrophils and conversion of prourokinase to urokinase in fibrinolysis.6-9

The SensoLyte® Rh110 Plasma Kallikrein Activity Assay Kit employs a substrate containing rhodamine 110 fluorophore (Rh110). Plasma kallikrein cleaves this Rh110 substrates to release a bright green fluorescent product that can be detected at 520 nm (Ex/Em: 496/520 nm).


  • Rh110 provides greater sensitivity and less interference from other reaction component
  • Detection of as low as 1ng/ml active plasma kallikrein
  • Detection of enzyme activity in purified enzyme preparations or biological samples. Can also be applied for compound screening
