| additional information | surface-catalyzed conversion of the blood zymogen factor XII, i.e. FXII or Hageman factor, to the enzyme FXIIa vis autoactivation is not specific for anionic surfaces. Surface activation is moderated by the protein composition of the fluid phase in which FXII autoactivation occurs by what appears to be a protein adsorption-competition effect. Contact activation of plasma coagulation is potentiated by assembly of activation-complex proteins, i.e. FXII, FXI, prekallikrein, and high-molecular-weight kininogen, directly onto activating surfaces (procoagulants) through specific protein/surface interactions, method evaluation, modelling and value of modeling hypotheticals, adsorption and coagulation kinetics, overview | Gallus gallus | ? | - |
