Data Examples

Western Blot Detection of Human and Mouse Transglutaminase 3/TGM3 by Western Blot. View Larger

Detection of Human and Mouse Transglutaminase 3/TGM3 by Western Blot. Western blot shows lysates of B16‑F1 mouse melanoma cell line, Bowes human melanoma cell line, and human skin tissue. PVDF Membrane was probed with 1 µg/mL of Human Transglutaminase 3/TGM3 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4604) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016).  For additional reference, Recombinant Human Transglutaminase 3/TGM3 (Catalog # 4604-TG) (10 ng/lane) uncleaved and cleaved by recombinant human Cathepsin were included. Specific bands were detected for uncleaved Transglutaminase 3/TGM3 at approximately 77 kDa (as indicated) and Transglutaminase 3/TGM3 cleavage products at approximately 50 and 30 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Transglutaminase 3/TGM3 in Human Skin. Transglutaminase 3/TGM3 was detected in immersion fixed paraffin-embedded sections of human skin using Human Transglutaminase 3/TGM3 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4604) at 3 µg/mL overnight at 4 °C. Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013). Tissue was stained using the Anti-Sheep HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS019) and counterstained with hematoxylin (blue). Specific staining was localized to cells in the hair follicle. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

Background: Transglutaminase 3/TGM3

Transglutaminase 3 (TG3), also known as epidermal Transglutaminase (Tgase E), belongs to the family of Transglutaminase enzymes that catalyze the posttranslational modification of proteins via calcium dependent cross-linking reactions (1-3). TG3 is involved in the formation of the cornified envelope in skin keratinocytes (4). It functions to cross-link structural proteins during epidermal terminal differentiation. TG3 has been implicated as the dominant autoantigen in dermatitis herpetiformis (5). TG3 activation requires proteolysis of the 77 kDa zymogen into two fragments of approximately 50 and 27 kDa to form the active enzyme (1).
