Related Product Information for TGM2 recombinant protein
Celiac disease is an enteropathy that is characterized by intestinal lesions of variable severity. Tissue-type transglutaminase (tTG) is believed to be the predominant autoantigen for celiac disease and the corresponding autoantibodies show higher sensitivity and specificity than anti-gliadin antibodies. Highly pure recombinant human tTG is now available to replace the traditionally used tTG fraction from guinea pig. Tissue-type transglutaminase antigens have been specifically modified for improved handling: exchange of an active site amino acid eliminates the protein cross-linking activity of the enzyme, while maintaining the native three-dimensional structure and the enzyme's secondary GTPase activity. This engineering assures reproducible properties of the antigen preparations through the absence of variable and ill-defined covalent aggregates of tTG antigen and host cell proteins.
Recombinant Human Tissue Transglutaminase produced in SF9 is a glycosylated, polypeptide chain having a molecular mass of 78.02kD. rHutTG is expressed with a -6xHis tag and purified by proprietary chromatographic techniques. By point mutation of the active center the catalytic transglutaminase activity has been eliminated, resulting in increased stability during storage and coating.
Product Categories/Family for TGM2 recombinant protein
NCBI Description
Transglutaminases are enzymes that catalyze the crosslinking of proteins by epsilon-gamma glutamyl lysine isopeptide bonds. While the primary structure of transglutaminases is not conserved, they all have the same amino acid sequence at their active sites and their activity is calcium-dependent. The protein encoded by this gene acts as a monomer, is induced by retinoic acid, and appears to be involved in apoptosis. Finally, the encoded protein is the autoantigen implicated in celiac disease. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]
Uniprot Description
TGM2: an enzyme of the transglutaminase family that catalyzes the crosslinking of proteins and the conjugation of polyamines to proteins. While the primary structure of transglutaminases is not conserved, they all have the same amino acid sequence at their active sites and their activity is calcium-dependent. The protein encoded by this gene acts as a monomer, is induced by retinoic acid, and appears to be involved in apoptosis. . Is the autoantigen in coeliac disease and plays a role in apoptosis, cellular differentiation and matrix stabilisation. Three alternatively spliced isoforms have been described.

Product Notes
The TGM2 tgm2 (Catalog #
AAA636550) is a Recombinant Protein produced from Sf9 insect cells and is intended for research purposes only. The product is available for immediate purchase. Suitable for use in Western Blot with monoclonal anti-hexa-His-tag antibody and standard ELISA (checker-board analysis of positive/negative sera panels, immuno-dot test). Also suitable for biotinylation and iodination. Dilution: ELISA: 0.6-1.4ug/ml (depending on the type of plate and coating buffer). Optimal dilutions to be determined by the researcher. Researchers should empirically determine the suitability of the TGM2 tgm2 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process.
It is sometimes possible for the material contained within the vial of
"Transglutaminase, Tissue, Recombinant Protein" to become dispersed throughout the inside of
the vial, particularly around the seal of said vial, during shipment and storage. We always
suggest centrifuging these vials
to consolidate all of the liquid away from the lid and to the bottom of the vial prior to
opening. Please be advised that
certain products may require dry ice for shipping and that, if this is the case, an
additional dry ice fee may also be
required.
