TGF-beta 3 Antibody Summary

Specificity
Detects TGF-beta 3 from multiple species in direct ELISAs and Western blots. In Western blots, less than 25% cross-reactivity with recombinant human (rh) TGF‑ beta 1.2 and rhTGF-beta 2 is observed, and less than 2% cross‑reactivity with recombinant amphibian TGF-beta 5 and recombinant human TGF-beta 1 is observed. Neutralizes the biological activity of TGF-beta 3 but not TGF-beta 1, TGF-beta 2, or TGF-beta 5.

Neutralization
Measured by its ability to neutralize TGF‑ beta 3 inhibition of IL‑4-dependent proliferation in the HT‑2 mouse T cell line. Tsang, M. et al. (1995) Cytokine 7:389. The Neutralization Dose (ND50) is typically 0.1-0.3 µg/mL in the presence of 0.1 ng/mL Recombinant Human TGF‑ beta 3 and 7.5 ng/mL Recombinant Mouse IL‑4.

Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

TGF‑ beta 3 Inhibition of IL‑4-dependent Cell Proliferation and Neutralization by TGF‑ beta 3 Antibody. Recombinant Human TGF-beta 3 (Catalog # 243-B3) inhibits Recombinant Mouse IL-4 (Catalog # 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 concen-trations of Mouse Anti-TGF-beta 3 Monoclonal Antibody (Catalog # MAB243). The ND50is typically 0.1-0.3 µg/mL.

TGF‑ beta 3 in Human Breast Cancer Tissue. TGF-beta 3 was detected in immersion fixed paraffin-embedded sections of human breast cancer tissue using Mouse Anti-TGF-beta 3 Monoclonal Antibody (Catalog # MAB243) at 5 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm in cancer cells. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

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‑ beta 3 (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).
