Scientific Data Images for TGF-beta 2 Antibody
Detection of Human TGF‑ beta2 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‑ beta2 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‑ beta2 at approximately 64 kDa (as indicated) using 5 µg/mL of Rabbit Anti-TGF‑ beta2 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.Applications for TGF-beta 2 Antibody
Application
Recommended Usage
Simple Western
5 µg/mL
Sample: Human heart tissue and human breast cancer tissue
Sample: Human heart tissue and human breast cancer tissue
Western Blot
0.1 µg/mL
Sample: Human heart tissue and human breast cancer tissue
Sample: Human heart tissue and human breast cancer tissue
Neutralization
Measured by its ability to neutralize TGF‑ beta2 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‑ beta2 and 7.5 ng/mL Recombinant Mouse IL‑4.
