Activation of factor XII by dextran sulfate: the basis for an assay of factor XII [PDF]

open access: yesBlood, 1983
A system was developed for studying the activation of factor XII (Hageman factor) in the presence of dextran sulfate (DS). Salient features of the system included low ionic strength (0.08), low concentration of factor XII (approximately 1/10,000 that in normal plasma), and an excess of exogenous prekallikrein (PK).

Factor XII – A Limitation for Divers? [PDF]

open access: yesPolish Hyperbaric Research, 2015
Abstract The lack of evidence for the tissue-factor dependent activation of the coagulation system and the release of thrombin on one hand, and a decreased concentration of factor XII after short term air, saturated air and heliox exposures, as well as an increased concentration of the plasmin-antiplasmin complex (PAP) after short dives

In vivo roles of factor XII [PDF]

open access: yesBlood, 2012
AbstractCoagulation factor XII (FXII, Hageman factor, EC = 3.4.21.38) is the zymogen of the serine protease, factor XIIa (FXIIa). FXII is converted to FXIIa through autoactivation induced by “contact” to charged surfaces. FXIIa is of crucial importance for fibrin formation in vitro, but deficiency in the protease is not associated with excessive ...

Inherited Factor XII Deficiency—What Is the Real Concern for Neuroanesthesiologist: Bleeding or Clotting

open access: yesJournal of Neuroanaesthesiology and Critical Care, 2020
Factor XII deficiency is a rare disorder that can complicate the perioperative management of a patient. Factor XII plays an important role in the activation of intrinsic pathway of coagulation; the deficiency, therefore, results in prolongation of ...

Establishment of the World Health Organization First International Standard for Factor XII, Plasma, Human

open access: yesFrontiers in Medicine, 2018
Until recently, the role of factor XII (FXII) in hemostasis was not considered to be important since patients with FXII deficiency do not present with bleeding.

Activity of factor XII‐Locarno [PDF]

open access: yesResearch and Practice in Thrombosis and Haemostasis, 2018
Factor XII (FXII) Locarno is a natural variant with proline replacing Arg353 at the activation cleavage site, preventing conversion to the fully active protease factor XIIa (FXIIa). Recently, we showed that FXII restricted to a single chain form (sc-FXII) by replacing Arg353 with alanine expresses proteolytic activity that is enhanced by cofactors such

Extracellular Vesicles Derived From Platelets, Red Blood Cells, and Monocyte-Like Cells Differ Regarding Their Ability to Induce Factor XII-Dependent Thrombin Generation

open access: yesFrontiers in Cell and Developmental Biology, 2020
As transmitters of biological information, extracellular vesicles (EVs) are crucial for the maintenance of physiological homeostasis, but also contribute to pathological conditions, such as thrombotic disorders.
