TGF-beta 1, 2, 3 Antibody Summary

Detects bovine, chicken, mouse, and human TGF-beta in ELISAs and Western blots. It recognizes human TGF-beta 1, TGF-beta 2, and TGF-beta 3.
Recombinant Monoclonal Mouse IgG1 Clone # 1D11R
Protein A or G purified from cell culture supernatant
Bovine bone-derived TGF-beta 1 and TGF-beta 2
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied as a 0.2 µm filtered solution in PBS.
Endotoxin Level
<0.10 EU per 1 μg of the antibody by the LAL method.


Recommended Concentration
Measured by its ability to neutralize TGF‑ beta 1 inhibition of IL‑4-dependent proliferation in the HT‑2 mouse T cell line. Tsang, M. et al. (1990) Lymphokine Res. 9:607. The Neutralization Dose (ND50) is typically 0.25-1.25 µg/mL in the presence of 1 ng/mL Recombinant Human TGF‑ beta 1 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 1 Inhibition of IL-4-dependent Cell Proliferation and Neutralization by TGF-beta 1, 2, 3 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 Mouse Anti-TGF-beta 1, 2, 3 Monoclonal Antibody (Catalog # MAB1835R). The ND50is typically0.25-1.25 µg/mL.Catalog # 240-B

Background: TGF-beta 1, 2, 3

TGF-beta 1, -2, and -3 are a closely related group of proteins (70‑80% sequence homology) that are produced by many cell types and function as growth and differentiation factors. The active forms of TGF-beta 1, -2, and -3 are disulfide-linked homodimers.
