Western blot - Anti-eIF4EBP1 antibody [Y329] (AB32024)

Lanes 1 - 4 : Merged signal (red and green). Green - ab32024 observed at 20 kDa. Red - loading control, ab8245, observed at 37 kDa.

ab32024 was shown to specifically react with elF4EBP1 in wild-type Hap1 cells. Wild-type and elF4EBP1 knockout samples were subjected to SDS-PAGE. ab32024 and ab8245 (loading control to GADPH) were diluted 1/5000 and 1/2000 respectively and incubated overnight at 4°C. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1/10000 dilution for 1 h at room temperature before imaging.

Western blot - Anti-eIF4EBP1 antibody [Y329] (AB32024)

Lanes 1-2 : Merged signal (red and green). Green - ab32024 observed at 13 kDa. Red - loading control ab8245 observed at 37 kDa.

ab32024 Anti-eIF4EBP1 antibody [Y329] was shown to specifically react with eIF4EBP1 in wild-type HeLa cells. Loss of signal was observed when knockout cell line ab264784 (knockout cell lysate ab257146) was used. Wild-type and eIF4EBP1 knockout samples were subjected to SDS-PAGE. ab32024 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) were incubated overnight at 4°C at 1 in 5000 Dilution and 1 in 20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye^® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye^® 680RD) preadsorbed (ab216776) secondary antibodies at 1 in 20000 dilution for 1 hour at room temperature before imaging.

Flow Cytometry (Intracellular) - Anti-eIF4EBP1 antibody [Y329] (AB32024)

Overlay histogram showing HAP1 wildtype (green line) and HAP1-EIF4EBP1 knockout cells (red line) stained with ab32024. The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Triton X-100 for 15 min. The cells were then incubated in 1x PBS / 10% normal goat serum to block non-specific protein-protein interactions followed by the antibody (ab32024, 0.1μg/ml) for 30 min at 22°C. The secondary antibody used was Alexa Fluor^® 488 goat anti-rabbit IgG (H&L) presorbed (ab150081) at 1/2000 dilution for 30 min at 22°C. A rabbit IgG isotype control antibody (ab172730) was used at the same concentration and conditions as the primary antibody (HAP1 wildtype - black line, HAP1-EIF4EBP1 knockout - grey line). Unlabelled sample was also used as a control (this line is not shown for the purpose of simplicity). Acquisition of >5,000 events were collected using a 50 mW Blue laser (488nm) and 530/30 bandpass filter. This antibody can also be used in HAP1 cells fixed with 4% formaldehyde (10 min) , permeabilized with 0.1% PBS-Triton X-100 for 15 min under the same conditions.
