Scientific Data Images for TGF-beta 3 Antibody
TGF‑ beta3 Inhibition of IL‑4-dependent Cell Proliferation and Neutralization by TGF‑ beta3 Antibody.
Recombinant Human TGF-beta 3 (243-B3) inhibits Recombinant Mouse IL-4 (404-ML) induced proliferation in the HT-2 mouse T cell line in a dose-dependent manner (orange line). Inhibition of Recombinant Mouse IL-4 (7.5 ng/mL) activity elicited by Recombinant Human TGF-beta 3 (0.1 ng/mL) is neutralized (green line) by increasing concentrations of TGF-beta 3 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-243-NA). The ND50 is typically 0.01-0.05 µg/mL.
TGF-beta 3 in Human Brain.
TGF-beta 3 was detected in immersion fixed paraffin-embedded sections of human brain using Goat Anti-TGF-beta 3 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-243-NA) at 5 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Goat IgG VisUCyte™ HRP Polymer Antibody (VC004). Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (CTS013). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to neuronal cell bodies. Staining was performed using our protocol for IHC Staining with VisUCyte HRP Polymer Detection Reagents.Applications for TGF-beta 3 Antibody

Background: TGF-beta 3
TGF-beta 3 (transforming growth factor beta 3) is one of three closely related mammalian members of the large TGF-beta superfamily that share a characteristic cystine knot structure (1‑7). TGF-beta 1, -2 and -3 are highly pleiotropic cytokines that are proposed to act as cellular switches that regulate processes such as immune function, proliferation and epithelial-mesenchymal transition (1‑4). Each TGF-beta isoform has some non-redundant functions; for TGF-beta 3, mice with targeted deletion show defects palatogenesis and pulmonary development (2). Human TGF-beta 3 cDNA encodes a 412 amino acid (aa) precursor that contains a 20 aa signal peptide and a 392 aa proprotein (8). A furin-like convertase processes the proprotein to generate an N-terminal 220 aa latency-associated peptide (LAP) and a C-terminal 112 aa mature TGF- beta3 (8, 9). Disulfide-linked homodimers of LAP and TGF-beta 3 remain non-covalently associated after secretion, forming the small latent TGF-beta 3 complex (8‑10). Covalent linkage of LAP to one of three latent TGF-beta binding proteins (LTBPs) creates a large latent complex that may interact with the extracellular matrix (9, 10). TGF-beta is activated from latency by pathways that include actions of the protease plasmin, matrix metalloproteases, thrombospondin 1 and a subset of integrins (10). Mature human TGF-beta 3 shows 100%, 99% and 98% aa identity with mouse/dog/horse, rat and pig TGF-beta 3, respectively. It demonstrates cross-species activity (1). TGF-beta 3 signaling begins with high-affinity binding to a type II ser/thr kinase receptor termed TGF-beta RII. This receptor then phosphorylates and activates a second ser/thr kinase receptor, TGF-beta RI (also called activin receptor-like kinase (ALK) -5), or alternatively, ALK-1.This complex phosphorylates and activates Smad proteins that regulate transcription (3, 11, 12). Contributions of the accessory receptors betaglycan (also known as TGF-beta RIII) and endoglin, or use of Smad-independent signaling pathways, allow for disparate actions observed in response to TGF-beta in different contexts (11).
