Transglutaminase 1 from Human keratinocyte, Recombinant

Cat No.
NATE-1724
Description
Transglutaminase 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. Transglutaminase is purified by IMAC to more than 90 % purity.
Abbr
TG1, Recombinant (Human keratinocyte)
Alias
TG1
Source
Insect cells
Species
Human
Applications
This procuct 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. This product may also be used for immunoprecipitation.
Appearance
White lyophilized solid.
Package
150 μg
Form
The transglutaminase is lyophilized from 50 mM Tris-HCl pH 8.0, 10 mM Glutathion.
Enzyme Commission Number
EC 2.3.2.13
Activity
> 8,000 U/mg [Activity is determined by measuring the rate of fluorescence enhancement after transglutaminase-catalyzed monodansylcadaverine-incorporation into N,N-dimethylated casein according to Lorand et al., Anal. Biochem. 44 (221-231)].
CAS No.
80146-85-6
Molecular Weight
90 kDa
Purity
> 90 % (visually by SDS-PAGE)
Unit Definition
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)].
Activators
Add 10 mM Ca2+ to activate transglutaminase.
Storage
Store at ≤ - 20°C. Store working aliquots at ≤ - 20°C. Avoid repeated freezing and thawing. Delivery at ambient temperature is possible
Synonyms
transglutaminase; EC 2.3.2.13; 80146-85-6; transglutaminase; Factor XIIIa; fibrinoligase; fibrin stabilizing factor; glutaminylpeptide γ-glutamyltransferase; polyamine transglutaminase; tissue transglutaminase; R-glutaminyl-peptide:amine γ-glutamyl transferase; protein-glutamine γ-glutamyltransferase; TG1
Reconstitution
Add the volume of H2O the protein is lyophilized from 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.
