Recombinant Anti-Cyclin E1 antibody [EPR194] (ab133266)

Lane 1: Wild-type HAP1 whole cell lysate (20 µg)
Lane 2: Cyclin E1 knockout HAP1 whole cell lysate (20 µg)
Lane 3: HeLa whole cell lysate (20 µg)
Lane 4: MCF7 whole cell lysate (20 µg)

Lanes 1 - 4: Merged signal (red and green). Green - ab133266 observed at 47 kDa. Red - loading control, ab9484, observed at 37 kDa.

Unpurified ab133266 was shown to recognize Cyclin E1 in wild-type cells as signal was lost at the expected MW in Cyclin E1 knockout cells. Additional cross-reactive bands were observed in the wild-type and knockout cells. Wild-type and Cyclin E1 knockout samples were subjected to SDS-PAGE. Ab133266 and ab9484 (Mouse anti-GAPDH 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.

Immunocytochemistry/ Immunofluorescence analysis of HeLa (Human cervix adenocarcinoma epithelial cell) cells labeling Cyclin E1 with Purified ab133266 at 1:1000 dilution (1.6μg/ml). Cells were fixed in 4% Paraformaldehyde and permeabilized with 0.1% tritonX-100. Cells were counterstained with Ab195889 Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker (Alexa Fluor^® 594) 1:200 (2.5 μg/ml). ab150077 Goat anti rabbit IgG(Alexa Fluor^® 488) was used as the secondary antibody at 1:1000 dilution. DAPI nuclear counterstain. PBS instead of the primary antibody was used as the secondary antibody only control.

Unpurified ab133266 staining Cyclin E1 in HeLa cells by ICC/IF (Immunocytochemistry/immunofluorescence). Cells were fixed with paraformaldehyde and permeabilized with 0.5% Triton X-100 in PBS. Samples were incubated with primary antibody (1/500 in PBS) for 1 hour at 22°C. ab150081, an Alexa Fluor^® 488-conjugated goat anti-rabbit IgG polyclonal (1/200) was used as the secondary antibody. Counterstained with DAPI.
