特徴

• F13B (coagulation factor XIII B chain) encodes coagulation factor XIII B subunit.
• Coagulation factor XIII is the last zymogen to become activated in the blood coagulation cascade.
• Plasma factor XIII is a heterotetramer composed of 2 A subunits and 2 B subunits.
• The A subunits have catalytic function, and the B subunits do not have enzymatic activity and may serve as a plasma carrier molecules.
• Platelet factor XIII is comprised only of 2 A subunits, which are identical to those of plasma origin.
• Upon activation by the cleavage of the activation peptide by thrombin and in the presence of calcium ion, the plasma factor XIII dissociates its B subunits and yields the same active enzyme, factor XIIIa, as platelet factor XIII.
• This enzyme acts as a transglutaminase to catalyze the formation of gamma-glutamyl-epsilon-lysine crosslinking between fibrin molecules, thus stabilizing the fibrin clot.
• Factor XIII deficiency is classified into two categories: type I deficiency, characterized by the lack of both the A and B subunits; and type II deficiency, characterized by the lack of the A subunit alone.
• These defects can result in a lifelong bleeding tendency, defective wound healing, and habitual abortion.
• Applications:Suitable for use in Western Blot, Immunohistochemistry and ELISA.
• Other applications not tested.
• Recommended Dilution:Western Blot: 1:500-1:2000Immunohistochemistry (paraffin): 1:100-1:300ELISA: 1:10,000Optimal dilutions to be determined by the researcher.
