Applications
  •  
    Recommended
    Concentration
    Sample
  • Western Blot
    0.1 µg/mL
    See below
  • Simple Western
    5 µg/mL
    See below
  • Neutralization
    Measured by its ability to neutralize TGF‑ beta 2 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 0.25-1.25 µg/mL in the presence of 1 ng/mL Porcine TGF‑ beta 2 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.
Data Examples
Detection of Human TGF‑ beta 2 by Western Blot. Western blot shows lysates of human heart tissue and human breast cancer tissue. PVDF membrane was probed with 0.1 µg/mL of Rabbit Anti-TGF‑ beta 2 Polyclonal Antibody (Catalog # AB-12-NA) followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # HAF008). A specific band was detected for TGF‑ beta 2 at approximately 70 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Detection of Human TGF‑ beta 2 by Simple WesternTM. Simple Western lane view shows lysates of human heart tissue and human breast cancer tissue, loaded at 0.2 mg/mL. A specific band was detected for TGF‑ beta 2 at approximately 64 kDa (as indicated) using 5 µg/mL of Rabbit Anti-TGF‑ beta 2 Polyclonal Antibody
(Catalog # AB-12-NA). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.        
TGF‑ beta 2 Inhibition of IL‑4-dependent Cell Proliferation and Neutralization by TGF‑ beta 2 Antibody. Porcine TGF‑ beta 2 (Catalog # 102-B2) 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 Porcine TGF‑ beta 2 (1 ng/mL) is neutralized (green line) by increasing concentrations of Rabbit Anti-TGF‑ beta 2 Polyclonal Antibody (Catalog # AB-12-NA). The ND50 is typically
0.25-1.25 µg/mL.

Background: TGF-beta 2
TGF-beta 2 (transforming growth factor beta 2) is one of three closely related mammalian members of the large TGF-beta superfamily that share a characteristic cysteine knot structure (1-7). TGF-beta 1, -2 and -3 are highly pleiotropic cytokines 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 2, mice with targeted deletion show defects in development of cardiac, lung, craniofacial, limb, eye, ear and urogenital systems (2). Human TGF-beta 2 cDNA encodes a 414 amino acid (aa) precursor that contains a 19 aa signal peptide and a 395 aa proprotein (8). A furin-like convertase processes the proprotein to generate an N-terminal 232 aa latency-associated peptide (LAP) and a C-terminal 112 aa mature TGF- beta 2 (8, 9). Disulfide-linked homodimers of LAP and TGF-beta 2 remain non-covalently associated after secretion, forming the small latent TGF-beta 1 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 2 shows 100% aa identity with porcine, canine, equine and bovine TGF-beta 2, and 97% aa identity with mouse and rat TGF-beta 2. It demonstrates cross-species activity (1). TGF-beta 2 signaling begins with binding to a complex of the accessory receptor betaglycan (also known as TGF-beta RIII) and a type II ser/thr kinase receptor termed TGF-beta RII. This receptor then phosphorylates and activates another ser/thr kinase receptor, TGF-beta RI (also called activin receptor-like kinase (ALK) -5), or alternatively, ALK-1. The whole complex phosphorylates and activates Smad proteins that regulate transcription (3, 11, 12). Use of other signaling pathways that are Smad-independent allows for disparate actions observed in response to TGF-beta in different contexts (11).
