Data Examples
Detection of Human Smad4 by Western Blot. Western blot shows lysates of HepG2 human hepatocellular carcinoma cell line and HEK293 human embryonic kidney cell line. PVDF membrane was probed with 0.5 µg/mL of Human Smad4 Monoclonal Antibody (Catalog # MAB20971) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for Smad4 at approximately 60 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: Smad4
Smads are a family of intracellular proteins that transmit transforming growth factor beta (TGF-beta ) superfamily signals from the cell surface to the nucleus. Upon signal-induced phosphorylation, Smad subunits associate with the common-mediator subunit, Smad4. This heteromeric complex then translocates into the nucleus to exert transcriptional comodulator activity.
