Scientific Data Images for Human/Mouse/Rat Transglutaminase 2/TGM2 Antibody
Detection of Human, Mouse, and Rat Transglutaminase 2/TGM2 by Western Blot.
Western blot shows lysates of HeLa human cervical epithelial carcinoma cell line, HepG2 human hepatocellular carcinoma cell line, mouse liver tissue, and rat liver tissue. PVDF membrane was probed with 0.5 µg/mL of Sheep Anti-Human/Mouse/Rat Transglutaminase 2/TGM2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4376) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (HAF016). A specific band was detected for Transglutaminase 2/TGM2 at approximately 85 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Detection of Human Transglutaminase 2/TGM2 by Simple WesternTM.
Simple Western lane view shows lysates of HeLa human cervical epithelial carcinoma cell line loaded at 0.2 mg/mL. A specific band was detected for Transglutaminase 2/TGM2 at approximately 82 kDa (as indicated) using 5 µg/mL of Sheep Anti-Human/Mouse/Rat Transglutaminase 2/TGM2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4376) followed by 1:50 dilution of HRP-conjugated Anti-Sheep IgG Secondary Antibody (HAF016). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.
Transglutaminase 2/TGM2 Specificity is Shown by Immunocytochemistry in Knockout Cell Line.
A549 WT and Transglutaminase 2/TGM2 KO cells were labelled with a green or a far-red fluorescent dye, respectively. Cells were stained with Sheep Anti-Human/Mouse/Rat Transglutaminase 2/TGM2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4376) followed by incubation with a donkey anti-sheep Alexa-fluor 555 coupled secondary antibody (upper panel). DAPI-only counterstained cells shown on a lower panel. Acquisition of the blue (nucleus-DAPI), green (identification of WT cells), red (antibody staining) and far-red (identification of KO cells) channels was performed. Representative images of the blue and red (grayscale) channels are shown. WT and KO cells are outlined with green and magenta dashed line, respectively. Primary antibody concentration used: 0.2 µg/mL. Image, protocol and testing courtesy of YCharOS Inc. (ycharos.com).

Background: Transglutaminase 2/TGM2
Transglutaminase 2 (TG2), encoded by the TGM2 gene, is also known as tissue transglutaminase (tTG), transgluytaminase C (TGC), and protein-glutamine-gamma -glutamyltransferase. It belongs to the family of transglutaminases that catalyze the posttranslational modification of proteins via calcium dependent cross-linking reactions (1-3). In addition to its function in protein cross-linking, TGM2 is also capable of hydrolyzing both GTP and ATP (4) and has intrinsic kinase activity (5). TGM2 has been implicated in a variety of human diseases including celiac disease, inclusion body myositis, atherosclerosis, and neurodegenerative diseases (6-7).
