Immunoprecipitation - Anti-Cdk4 antibody [EPR17525] (AB199728)

Cdk4 was immunoprecipitated from 1mg NIH/3T3 (Mouse embryonic fibroblast cell line) whole cell lysate with ab199728 at 1/50 dilution. Western blot was performed from the immunoprecipitate using ab199728 at 1/1000 dilution. Anti-Rabbit IgG (HRP) specific to the non-reduced form of IgG was used as secondary antibody at 1/1500 dilution.

Lane 1 : NIH/3T3 whole cell lysate, 10 (Input).

Lane 2 : ab199728 IP in NIH/3T3 whole cell lysate.

Lane 3 : Rabbit IgG,monoclonal [EPR25A]- Isotype Control (ab172730) instead of ab199728 in NIH/3T3 whole cell lysate.

Western blot - Anti-Cdk4 antibody [EPR17525] (AB199728)

ab199728 was shown to specifically react with CDK4 when CDK4 knockout samples were used. Wild-type and CDK4 knockout samples were subjected to SDS-PAGE. ab199728 and ab8226 (loading control to beta actin) were both diluted at 1/1000 and incubated overnight at 4°C. Blots were developed with goat anti-rabbit IgG (H + L) and goat anti-mouse IgG (H + L) secondary antibodies at 1/10 000 dilution for 1 h at room temperature before imaging.

Lanes 1 - 3 : Merged signal (red and green). Green - ab199728 observed at 34 kDa. Red - loading control, ab18058, observed at 130 kDa.

ab199728 was shown to specifically recognize Cdk4 in wild-type HAP1 cells along with additional cross-reactive bands. No band was observed when Cdk4 knockout samples were examined. Wild-type and Cdk4 knockout samples were subjected to SDS-PAGE. ab199728 and ab18058 (Mouse anti Vinculin loading control) were incubated overnight at 4°C at 1/1000 dilution and 1/20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye^® 800CW) preabsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye^® 680RD) preabsorbed (ab216776) secondary antibodies at 1/20000 dilution for 1 hour at room temperature before imaging.
