transglutaminase 7 TG7 by Zedira
Molecular Weight
81 kDa
Source
Recombinantly produced in E. coli
Purity
> 90 % (visually by SDS-PAGE)
Activation
His6-rhTG7 is a Ca2+-dependent enzyme.
Add 10 mM Ca2+ to activate His6-rhTG7.
Specific Activity
> 1000 U/mg [Activity is determined by measuring the rate of fluorescence enhancement after His6-rhTG7-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)].
Appearance
White lyophilized solid
Description
His6-rhTG7 is based on the TGM7-gene on plasmid pCRII-hTGz cl.14 (isolated by Daniel Aeschlimann), corrected by the insertion of a C at position 1169. It is N-terminally fused to a hexahistidine-tag.
Reagents
The Transglutaminase is lyophilized from 50 mM Tris-HCl pH 8.
Reconstitution
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.
Application
His6-rhTG7 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-rhTG7 may also be used for immunoprecipitation.
Storage
Store at ≤ -20°C.
Store working aliquots at ≤ -20°C. Avoid repeated freezing and thawing.
Delivery at ambient temperature is possible
