Western blot analysis of SMAD3 using anti-SMAD3 antibody (PB0445). The sample well of each lane was loaded with 30 ug of sample under reducing conditions.
Lane 1: human A549 whole cell lysates,
Lane 2: human RT4 whole cell lysates,
Lane 3: human A431 whole cell lysates,
Lane 4: human PC-3 whole cell lysates,
Lane 5: rat brain tissue lysates,
Lane 6: rat ovary tissue lysates,
Lane 7: mouse brain tissue lysates.
After electrophoresis, proteins were transferred to a membrane. Then the membrane was incubated with rabbit anti-SMAD3 antigen affinity purified polyclonal antibody (PB0445) at a dilution of 1:1000 and probed with a goat anti-rabbit IgG-HRP secondary antibody (Catalog # BA1054). The signal is developed using ECL Plus Western Blotting Substrate (Catalog # AR1197). A specific band was detected for SMAD3 at approximately 50-55 kDa. The expected band size for SMAD3 is at 46 kDa.

IHC analysis of SMAD3 using anti-SMAD3 antibody (PB0445).
SMAD3 was detected in a paraffin-embedded section of human liver cancer tissue. The tissue section was incubated with rabbit anti-SMAD3 Antibody (PB0445) at a dilution of 1:200 and developed using HRP Conjugated Rabbit IgG Super Vision Assay Kit (Catalog # SV0002) with DAB (Catalog # AR1027) as the chromogen.

ICC/IF analysis of SMAD3 using anti-SMAD3 antibody (PB0445) and anti-Alpha Tubulin antibody (M03989-3).
SMAD3 was detected in an immunocytochemical section of A549 cells. The section was incubated with rabbit anti-SMAD3 Antibody (PB0445) at a dilution of 1:100. FITC Conjugated AffiniPure Goat Anti-rabbit IgG (H+L) Secondary Antibody (green) (Catalog # BA1105) and Cy3-conjugated Anti-mouse IgG Secondary Antibody (red) (Catalog # BA1031) were used as secondary antibody.
