Prekallikrein (PK), also known as Fletcher factor, is a serine protease that complexes with high molecular-weight kininogen.
Prekallikrein is the zymogen form of plasma kallikrein, which is a serine protease that activates kinins. It is cleaved to produce kallikrein by activated FXII (Hageman factor).
The protein is > 95% pure according to SDS-PAGE gels and shows no reduction when incubated with 2-mercaptoethanol.
