WebFletcher factor - factor found in coagulation studies, revealing a slow contact activation but not associated with bleeding abnormalities. Synonym(s): prekallikrein WebJan 1, 2016 · Plasma kallikrein (EC 3.4.21.34) is transcribed by KLKB1 located on chromosome 4q35 in human. In mammals, KLKB1 is duplicated to form factor XI (F11) by tandem duplication [1]. KLKB1 in plasma is mostly in an inactive form known as prekallikrein and it is activated by contact activation involving HMW KNG and factor XII.

Prekallikrein is converted to kallikrein by Factor XIIa. Once formed, kallikrein enhances the activation of Factor XII and (with Factor XIIa) converts HWMK into bradykinin, which is an important mediator of ... WebFletcher factor-deficient plasma is deficient in prekallikrein and therefore generates no bradykinin upon activation with kaolin. It also possesses a diminished rate of kaolin-activable coagulation and fibrinolysis and possesses a defect in kaolin-activable chemotactic activity. These abnormalities are also corrected by reconstitution with ... easy new orleans pralines
