TGF‑ beta 1 Inhibition of IL‑4-dependent Cell Proliferation and Neutralization by TGF‑ beta 1/1.2 Antibody. Recombinant Human TGF-beta 1 (Catalog # 240-B) 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 1 (1 ng/mL) is neutralized (green line) by increasing concentrations of Chicken Anti-TGF-beta 1/1.2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-101-NA). The ND50 is typically ≤100 ng/mL.

Background: TGF-beta 1/1.2

TGF-beta 1 (transforming growth factor beta 1) is one of three closely related mammalian members of the large TGF-beta superfamily that share a characteristic cystine knot structure. 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. Each TGF-beta isoform has some non-redundant functions; for TGF-beta 1, mice with targeted deletion show defects in hematopoiesis and endothelial differentiation, and die of overwhelming inflammation. Human TGF-beta 1 cDNA encodes a 390 amino acid (aa) precursor that contains a 29 aa signal peptide and a 361 aa proprotein. A furin-like convertase processes the proprotein to generate an N-terminal 249 aa latency-associated peptide (LAP) and a C-terminal 112 aa mature TGF- beta 1. Disulfide-linked homodimers of LAP and TGF-beta 1 remain non-covalently associated after secretion, forming the small latent TGF-beta 1 complex. 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. TGF-beta is activated from latency by pathways that include actions of the protease plasmin, matrix metalloproteases, thrombospondin 1 and a subset of integrins. Mature human TGF-beta 1 shares 100% aa identity with pig, dog and cow TGF-beta 1, and 99% aa identity with mouse, rat and horse TGF-beta 1. It demonstrates cross-species activity. TGF-beta 1 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. 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.

FAQs

  1. Does AF-101-NA detect other isoforms of TGF-beta?

    • Cross-reactivity testing results are listed in the Specificity section on the Product Datasheet: less than 15% cross-reactivity with recombinant amphibian TGF-beta 5 and less than 2% with TGF-beta 2 and TGF-beta 3, have been observed, as measured by direct ELISA.

  2. Can pro-IL-1 beta be detected by Catalog #s AF-201-NA and MAB601 ?

    • The amino acid sequence present in mature IL-1 beta (Ala117-Ser269) is also present in pro IL-1 beta. So in theory, both Catalog #s AF-201-NA and MAB601 should detect the pro form of IL-1 beta. The results would depend on whether the pro form is abundantly present in the sample type being evaluated.
