This product is a recombinant rabbit monoclonal antibody.
Our Abpromise guarantee covers the use of ab53280 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|WB||1/10000. Detects a band of approximately 52 kDa (predicted molecular weight: 54 kDa).
For unpurified use at 1/25,000 - 1/50,000.
For unpurified use at 1:70.
ab172730 - Rabbit monoclonal IgG, is suitable for use as an isotype control with this antibody.
|ICC/IF||1/100 - 1/500.|
Blocking and diluting buffer: 5% NFDM/TBST.
ab53280 (purified) at 1:20 dilution (0.2μg) immunoprecipitating Cytokeratin 8 in HeLa whole cell lysate.
Lane 1 (input): HeLa (Human cervix adenocarcinoma epithelial cell) whole cell lysate, 10μg
Lane 2 (+): ab53280 & HeLa whole cell lysate
Lane 3 (-): Rabbit monoclonal IgG (ab172730) instead of ab53280 in HeLa whole cell lysate
For western blotting, VeriBlot for IP secondary antibody (HRP) (ab131366) was used as the secondary antibody at 1:1000 dilution.
Blocking and diluting buffer: 5% NFDM/TBST.
Immunocytochemistry/Immunofluorescence analysis of HeLa (human cervix adenocarcinoma) labelling Cytokeratin 8 with purified ab53280 at 1/500. Cells were fixed with 4% Paraformaldehyde and permeabilised by 0.1% tritonX-100. An Alexa Fluor® 488-conjugated goat anti-rabbit IgG (1/1000) was used as the secondary antibody (Ab150077). Nuclei counterstained with DAPI (blue).

Unpurified ab53280 staining Cytokeratin 8 in Mouse liver tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with formalin and blocked with 10% serum for 20 minutes at 23°C; antigen retrieval was by heat mediation in a citrate buffer. Samples were incubated with primary antibody (1/75 in TBS + 1% BSA) for 1 hour at 23°C. A Biotin-conjugated Goat anti-rabbit IgG polyclonal (1/500) was used as the secondary antibody.

Overlay histogram showing HeLa cells stained with unpurified ab53280 (red line). The cells were fixed with 2% PFA (room temperature, 30 min) and then permeabilized with 1% FACS permeabilizing solution for 30 min. The cells were then incubated in 3% FBS in 1X PBS followed by the antibody (ab53280, 1/20 dilution) for 1 hour at room temperature. The cells were then incubated for 30 min at room temperature with the secondary antibody. An isotype control antibody (black line) was used and an unlabelled sample (blue line) was also used as a control.
