Add 10 mM Ca2+ to activate His6-rhTG1.
> 2,500 U/mg [Activity is determined by measuring the rate of fluorescence enhancement after His6-rhTG1-catalyzed monodansylcadaverine-incorporation into N,N-dimethylated casein according to Lorand et al., Anal. Biochem. 44 (221-231)]. 
1 U is defined as the increase in fluorescence intensity of 1 a.u./min (measured on a Cary eclipse fluorescence spectrophotometer, Varian; λex = 332 nm, λem = 500 nm; band filter = 5 nm; detector strength = 600 V; temperature = 37°C, assay volume = 1 ml)].
White lyophilized solid.
His6-rhTG1 is based on the TGM1-allele from I.M.A.G.E.-clone IRAKp961M1628 isolated from human skin squamous cell carcinoma. It is N-terminally fused to a hexahistidine-tag resulting in the encoded N-terminal amino acid sequence MHHHHHHMDGPR. His6-rhTG1 is purified by IMAC to more than 90 % purity.
The Transglutaminase is lyophilized from 50 mM Tris-HCl pH 8.0, 10 mM Glutathion
Add the volume of water specified in the certificate of analysis under aliquotation to the vial of lyophilized powder. Rotate vial gently until solid dissolves. After reconstitution the solution should be cooled on ice for short term storage.
His6-rhTG1 catalyzes acyl transfer reactions from glutamin 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. His6-rhTG1 may also be used for immunoprecipitation.
Store at ≤ - 20°C. Store working aliquots at ≤ - 20°C. Avoid repeated freezing and thawing.
Delivery at ambient temperature is possible
