High molecular weight kininogen test
WebHigh molecular weight kininogen (HMWK) deficiency is an autosomal recessive coagulation defect. It is known by a variety of names, including Fitzgerald trait, Flaujeac trait, and Williams trait. Patients with HWMK deficiency do not have a hemorrhagic tendency, but they exhibit abnormal surface-mediated activation of fibrinolysis. WebPlasma prekallikrein (amidolytic), high molecular weight kininogen (HK, coagulant) and cleavage of HK (western blot) were assayed to detect K-K activation. Results —Liver and spleen weights were significantly higher, and body weights and haematocrit values were significantly lower in the indomethacin group than in the control group.

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 … WebJan 1, 2024 · High molecular-weight (HMW) and low molecular-weight (LMW) KNGs are formed by the alternative splicing of kng1 in mammals. HMW-KNG interacts with plasma kallikrein to produce bradykinin (BK) and is involved in the contact activation of the blood coagulation process. LMW-KNG interacts with tissue kallikreins to produce [Lys0]-BK.
WebThe PPK synthesized in hepatocytes is secreted into the blood where it circulates at a concentration of 35–50 mg l −1 mainly as a complex with high-molecular-weight kininogen (HMWK; H-kininogen). Two forms of PPK with different carbohydrate contents (Mr = 85 and 88 kDa) exist in blood plasma. PPK is a single-chain protein with 619 amino acids. WebChromogenix Coamatic® Antithrombin is a chromogenic assay kit for in vitro diagnostic determination of antithrombin activity in human plasma. The use of factor Xa in preference to thrombin eliminates interference from heparin cofactor II and thrombin inhibitors.
