prostate transglutaminase TG4 T042 by Zedira
Molecular Weight
78 kDa
Source
Recombinantly produced in E. coli
Purity
> 95 % (visually by SDS-PAGE)
Activation
Add 10 mM Ca2+ to activate His6-rhTG4.
Activity
[Activity is determined by measuring the rate of fluorescence enhancement after His6-rhTG4-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 with Transglutaminase Assay Kit, Zedira, Product code T036].
Appearance
White lyophilized solid.
Description
His6-rhTG4 is based on clone IMAGp958A10818Q2. It is N-terminally fused to a hexahistidine-tag resulting in the encoded N-terminal amino acid sequence MHHHHHHAEELLL…. His6-rhTG4 is produced in E. coli and purified by ion metal chelating chromatography to more than 95 % purity.
Reagents
The Transglutaminase is lyophilized from 10 mM Tris-HCl pH 8.1, 150 mM NaCl, 5 mM DTT, 1 mM EDTA. 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
His6-rhTG4 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. His6-rhTG4 may also be used for immunoprecipitation.
Storage
Store at ≤ - 20°C.
Store working aliquots at . - 20°C. Avoid repeated freezing and thawing.
Delivery is possible at ambient temperature
