Western blot analysis of human TGF beta-1 was performed by loading 10ul of human serum from patients with multiple sclerosis (MS), leukemia, or asthma (left panel) and 2ug and 1ug of recombinant human TGF beta-1 protein (right panel) per well on a 4-20% Tris-HCl polyacrylamide gel. Proteins were transferred to a PVDF membrane and blocked with StartingBlock (TBS) Blocking Buffer (Product # 37542) for at least 1 hour. The membrane was probed with a TGF beta-1 monoclonal antibody (Product # MA1-169) at a concentration of 5ug/ml overnight at 4C on a rocking platform, washed in TBS-0.1%Tween-20, and probed with a goat anti-mouse IgG-HRP secondary antibody (Product # 31430) at a dilution of 1:10,000 for at least 1 hour. Chemiluminescent detection was performed using SuperSignal West Dura (Product # 34075).

TGF beta-1 is a polypeptide member of the transforming growth factor beta superfamily of cytokines found almost ubiquitously in tissues. Transforming growth factor (TGF-b) is stored in the extracellular matrix as a latent complex with its prodomain. Activation of TGF-b1 requires the binding of aV integrin to an RGD sequence in the prodomain and exertion of force on this domain, which is held in the extracellular matrix by latent TGF-b binding proteins. Latent forms are complexes of TGF-beta, an aminoterminal portion of the TGF-beta precursor, designated TGF-LAP (TGF-latency associated peptide), and a specific binding protein known as LTBP.
