ab28379 staining Smad3 in Mouse brain tissue sections by Immunohistochemistry (IHC-Fr - frozen sections). Tissue was fixed with paraformaldehyde and blocked with 10% serum for 60 minutes at 22°C. Samples were incubated with primary antibody (1/100) for 12 hours at 4°C. An AlexaFluor®488-conjugated Mouse anti-rabbit polyclonal (1/500) was used as the secondary antibody.
Chromatin was prepared from the nuclear cell lysate of a human myofibroblast cell line according to the X-ChIP protocol; cross-linking with formaldehyde for 10 minutes. ab28379 was diluted 1/16 (RIPA 0.1% SDS) and incubated with the sample for 16 hours at 4°C. ab28379 IP was used as the positive control and rabbit IgG pool IP was used as the negative control. Smad3 expression was enhanced by 2ng/ml TGFbeta 2. The immunoprecipitated DNA was quantified by real time PCR.
ab28379 staining Smad3 in human Human TII Pneumocyte A549 cells by Immunocytochemistry/ Immunofluorescence. Cells were fixed with paraformaldehyde and permeabilized with 0.1% Triton x100 before blocking with 3% BSA was done for 1 hour at RT. Samples were incubated with primary antibody (1/200: in 3% BSA in 1x PBST) for 24 hours at 4°C. An TRITC-conjugated goat polyclonal to rabbit IgG was used as secondary antibody at 1/200 dilution.
