Polyclonal

Rabbit Ig

Rabbit

This F13B antibody is generated from rabbits immunized with a KLH conjugated synthetic peptide between 151-179 amino acids from the N-terminal region of human F13B.

Peptide Affinity Purified Rabbit Polyclonal Antibody (Pab)

Purified polyclonal antibody supplied in PBS with 0.09% (W/V) sodium azide. This antibody is purified through a protein A column, followed by peptide affinity purification.

Vial Concentration: 0.5 (lot specific)

Maintain refrigerated at 2-8 degree C for up to 6 months. For long term storage store at -20 degree C in small aliquots to prevent freeze-thaw cycles.

Small volumes of anti-F13B antibody vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.

This gene 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.

F13B: The B chain of factor XIII is not catalytically active, but is thought to stabilize the A subunits and regulate the rate of transglutaminase formation by thrombin. Defects in F13B are the cause of factor XIII subunit B deficiency (FA13BD). FA13BD is an autosomal recessive disorder characterized by a life-long bleeding tendency, impaired wound healing and spontaneous abortion in affected women.
