Product Overview
This rabbit polyclonal antibody recognizes protein-glutamine gamma-glutamyltransferase 2 (gene TGM2) in human, mouse and rat samples and is validated for IHC and Western blot. The predicted molecular weight is 77.3 kDa, and the supplier reports an observed band at about 77 kDa.
Transglutaminase 2 (TGM2, tissue transglutaminase) is a calcium-dependent enzyme that forms covalent isopeptide cross-links between glutamine and lysine residues or attaches polyamines to proteins. Widely expressed inside cells and in the extracellular matrix, it influences matrix stabilization, cell adhesion, apoptosis and wound repair. TGM2 is also the autoantigen targeted in celiac disease and is studied in fibrosis and cancer.

Validated Applications
| Western blot | 0.1–0.5 µg/mL (Human, Mouse, Rat) |
|---|---|
| IHC (paraffin sections) | 2–5 µg/mL (Human) |
Samples with a confirmed band (WB): human SiHa cells, human A549 cells, rat kidney tissue, rat lung tissue, mouse kidney tissue, mouse lung tissue.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 10% SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Samples with confirmed staining (IHC): human placenta tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Conditions in the example images (IHC): heat-mediated antigen retrieval in EDTA buffer (pH 8.0).
Immunogen
Synthetic peptide from the N-terminal region of human TGM2. It differs from the mouse sequence at five residues.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places protein-glutamine gamma-glutamyltransferase 2 in the cytoplasm, nucleus, chromosome and cell membrane. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
