Recombinant Anti-Cdc25C antibody [E302] (ab32444)

Blocking and diluting buffer 5% NFDM/TBST

Immunohistochemical analysis of paraffin embedded human pancreas tissue section labelling Cdc25C with purified ab32444 at dilution of 1/2500. The secondary antibody used was Goat Anti-Rabbit IgG H&L (HRP) (ab97051), at dilution of 1/500. The sample was counter-stained with hematoxylin. Antigen retrieval was perfomed using Tris-EDTA buffer, pH 9.0. PBS was used instead of the primary antibody as the negative control and is shown in the inset.

Immunocytochemistry/Immunofluorescence analysis of HeLa (human cervix adenocarcinoma) cells labelling Cdc25C with purified ab32444 at 1/400. Cells were fixed with 4% Paraformaldehyde and permeabilized with 0.1% Triton X-100. ab150077, Alexa Fluor® 488-conjugated goat anti-rabbit IgG (1/1000) was used as the secondary antibody. The cells were co-stained with ab7291, a mouse anti-tubulin antibody (1/1000) using ab150120, an Alexa Fluor® 594-conjugated goat anti-mouse IgG (1/1000) as the secondary. Nuclei couterstained with DAPI (blue).

For negative control 1, rabbit primary antibody was used, followed by anti-mouse secondary antibody (ab150120). For negative control 2, mouse primary antibody (ab7291) was used followed by anti-rabbit secondary antibody (ab150077). 

Flow Cytometry analysis of K562 (human chronic myelogenous leukemia) cells labelling Cdc25C with purified ab32444 at 1/180 (red). Cells were fixed with 4% paraformaldehyde. Alexa Fluor^® 488-conjugated goat anti-rabbit IgG (1/500) was used as the secondary antibody. Black - Isotype control, rabbit monoclonal IgG. Blue - Unlabelled control, cells without incubation with primary and secondary antibodies.

Ab32444 (purified) at 1/30 immunoprecipitating Cdc25C in HeLa (human cervix adenocarcinoma) whole cell lysate.

Lane 1 (input): HeLa (human cervix adenocarcinoma) whole cell lysate

Lane 2 (+): ab32444 + HeLa (human cervix adenocarcinoma) whole cell lysate

Lane 3 (-): Rabbit monoclonal IgG (ab172730) instead of ab32444 in HeLa (human cervix adenocarcinoma) whole cell lysate

For western blotting, ab131366 VeriBlot for IP Detection Reagent (HRP) was used for detection (1/10000).

Blocking buffer and concentration: 5% NFDM/TBST.

Diluting buffer and concentration: 5% NFDM /TBST.

Lane 1: Wild-type HAP1 cell lysate (20 µg)
Lane 2: Cdc25C knockout HAP1 cell lysate (20 µg)
Lane 3: HeLa cell lysate (20 µg)
Lane 4: Hu bladder cell lysate (20 µg)
Lanes 1 - 4: Merged signal (red and green). Green - ab32444 observed at 55 kDa. Red - loading control, ab8245, observed at 37 kDa.

ab32444 was shown to recognize Cdc25C when Cdc25C knockout samples were used, along with additional cross-reactive bands. Wild-type and Cdc25C knockout samples were subjected to SDS-PAGE. ab32444 and ab8245 (loading control to GAPDH) were diluted at 1/2500 and 1/10 000 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.

Blocking and diluting buffer 5% NFDM/TBST

Immunohistochemical analysis of paraffin-embedded human urinary bladder carcinoma unpurified ab32444 at 1/250 dilution.

Flow cytometry analysis of HeLa cells, staining Cdc25C with unpurified ab32444.

Cells were fixed with formaldehyde and permeabilized with 90% methanol. Samples were incubated with primary antibody (1/20 in PBS + 10% goat serum) for 1 hour at 23°C. A FITC-conjugated goat anti-rabbit polyclonal IgG (1/1000) was used as the secondary antibody.
