    Predicted band size : 27 kDa
    Observed band size : 24 kDa (why is the actual band size different from the predicted?)
  • ICC/IF image of ab77772 stained MCF7 cells. The cells were 4% PFA fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab77772, 5µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM. This antibody also gave a positive result in 4% PFA fixed (10 min) HeLa and Hek293 cells at 5µg/ml, and in 100% methanol fixed (5 min) MCF7 cells at 5µg/ml.
  • IHC image of RPS3 staining in human liver carcinoma formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab77772, 5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

Thank you for your answer.

I would recommend to include a positive control in the experiment, where the expression of RPS3 is known to be expressed, such as liver tissue or cells (HepG2). This way there will be no ambiguity on the results. Read More

Thank you for your inquiry.

We have tested the ab77772 in immunocytochemistry and can therefore guarantee that it will work in this application. As I am not an expert in stem cell biology, I would recommend to check the literature to see whet...

Thank you for your enquiry.

For ab77772, I am afraid that we have not tested for isoform detection. I did a sequence comparison with RPS3A protein sequence and found that the homology is only 12%. Therefore, it is unlikely that there will be...
