Scientific Data Images for TGF‑ beta 2 Antibody

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 Goat Anti-TGF-beta 2/Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-302-NA). The ND₅₀ is typically 0.0100-0.100 µg/mL.

Applications for TGF‑ beta 2 Antibody

Application

Recommended Usage

Western Blot

0.1 µg/mL
Sample: Recombinant Human TGF-beta 2 (Catalog # 302-B2)

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 0.0100-0.100 µg/mL in the presence of 1 ng/mL Porcine TGF‑ beta 2 and 7.5 ng/mL Recombinant Mouse IL‑4.

Formulation, Preparation, and Storage

Purification

Antigen Affinity-purified

Reconstitution

Reconstitute at 0.2 mg/mL in sterile PBS. For liquid material, refer to CoA for concentration.

Formulation

Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. See Certificate of Analysis for details.
*Small pack size (-SP) is supplied either lyophilized or as a 0.2 µm filtered solution in PBS.

Shipping

Lyophilized product is shipped at ambient temperature. Liquid small pack size (-SP) is shipped with polar packs. Upon receipt, store immediately at the temperature recommended below.

Stability & Storage

Use a manual defrost freezer and avoid repeated freeze-thaw cycles.

12 months from date of receipt, -20 to -70 °C as supplied.
1 month, 2 to 8 °C under sterile conditions after reconstitution.
6 months, -20 to -70 °C under sterile conditions after reconstitution.

Calculators

The reconstitution calculator allows you to quickly calculate the volume of a reagent to reconstitute your vial. Simply enter the mass of reagent and the target concentration and the calculator will determine the rest.

Background: TGF-beta 2

TGF- beta 2 (transforming growth factor beta 2) is a highly pleiotropic cytokine with important functions during cardiac, lung, craniofacial, limb, eye, ear, and urogenital system development. It forms a latent complex with LAP and one of the LTBP TGF-beta binding proteins. The active protein is released by Plasmin, MMP, Thrombospondin 1, or Integrin action. TGF-beta 2 signals through TGF-beta RII, Betaglycan, and either TGF-beta RI/ALK-5 or ALK-1.
