Description
Recombinant dog Factor XIII is a homodimer (a2) composed of two chains held together by non covalent bonds. After activation of the zymogen by Thrombin and Ca2+ to its active form (a*2, Factor XIIIa), Factor XIIIa catalyzes the formation of covalent bridges (ε-(γ-glutamyl) lysine bonds) between fibrin units to increase the elasticity of the clot network. The resulting crosslinked fibrin is insoluble and resistant to lysis.
Reagents
The recombinant dog Factor XIII is lyophilized from 20 mM Tris- HCl pH 7.5, 150 mM NaCl, 1 mM EDTA, 1 mM DTT. Sample contains maltodextrin.
Reconstitution
Add the volume of H2O the protein is lyophilized from (see Certificate of Analysis) to the vial of lyophilized powder. Rotate vial gently until solid dissolves. After reconstitution the solution should be stored frozen in working aliquots. Keep cooled on ice for short term storage.
Application
clFXIIIa catalyzes acyl transfer reactions from glutamine residues in proteins or peptides to primary amines, e. g. the formation of ε-(γ-glutamyl) lysine bonds between proteins by transferring the acyl group of a peptide-bound glutamine residue to the primary amino group of a peptide-bound lysine residue.
Storage
Storage for several months is possible at ≤ - 20°C. 
Delivery is possible at ambient temperature
