Mouse TGF‑ beta 2 Antibody

Detection of Human and Mouse TGF‑ beta 2 by Western Blot.

Western blot shows lysates of Y-79 human retinoblastoma cell line, HUVEC human umbilical vein endothelial cells, NIH-3T3 mouse embryonic fibroblast cell line, 4T1 mouse breast cancer cell line, and NMuMG mouse mammary gland epithelial cell line. PVDF membrane was probed with 2 µg/mL of Rat Anti-Mouse TGF-beta 2 Monoclonal Antibody (Catalog # MAB73461) followed by HRP-conjugated Anti-Rat IgG Secondary Antibody (Catalog # HAF005). A specific band was detected for TGF-beta 2 at approximately 52 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

TGF‑ beta 2 in Mouse Embryo.

TGF-beta 2 was detected in immersion fixed frozen sections of mouse embryo (15 d.p.c.) using Rat Anti-Mouse TGF-beta 2 Monoclonal Antibody (Catalog # MAB73461) at 25 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Rat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS017) and counterstained with hematoxylin (blue). Specific staining was localized to neuronal processes.

Detection of Human TGF-beta 2 by Western Blot

LOXL2 acts with TGF-beta through PI3K/ATK/mTORC1 signalling to control myofibroblast transformation and migration.(a) Western blot analysis of LOXL2, SMAD2, p-SMAD2 and GAPDH in human primary cardiac fibroblasts transfected with control (Ctrl) or LOXL2 siRNA.
