WebHigh molecular weight kininogen is known to be cleaved by plasma kallikrein to form its 68 kDa cleavage product after contact system activation. High molecular weight kininogen was rare in SLE patient plasmas, except for small amounts detected in plasmas from patients 107, 127, 34.2, and 113 ( Fig. 4 B, lanes 2, 3, 6, and 10). WebHMW kininogen is present at about 70 μg/mL and has a molecular weight of approximately 110 000. 15 Its cofactor activity is thought to be surface dependent and, in vitro, negatively charged surfaces have been shown to enhance this activity.

WebHuman Kininogen quantitates human Kininogen in serum, plasma, supernatant. The assay will exclusively recognize both natural and recombinant human Kininogen. Target information This gene uses alternative splicing to generate two different proteins- high molecular weight kininogen (HMWK) and low molecular weight kininogen (LMWK). WebHigh-molecular-weight kininogen ( HMWK or HK) is a circulating plasma protein which participates in the initiation of blood coagulation, and in the generation of the vasodilator … WebDomains. InterPro. High-molecular-weight kininogen ( HMWK or HK) is a circulating plasma protein which participates in the initiation of blood coagulation, and in the generation of the vasodilator bradykinin via the kallikrein-kinin system. HMWK is inactive until it either adheres to binding proteins beneath an endothelium disrupted by injury ... greater than solomon kjv
