    Annexin A2 overexpression lysate (ab94080) at 1/5000 dilution
    Developed using the ECL technique

    Performed under reducing conditions.

    Predicted band size : 41 kDa
    Observed band size : 37,41 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 100 kDa,15 kDa,250 kDa. We are unsure as to the identity of these extra bands.

    Exposure time : 3 minutes
  • ICC/IF image of ab74777 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 (ab74777, 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) HepG2 cells at 5µg/ml, and in 100% methanol fixed (5 min) HepG2 and MCF7 cells at 5µg/ml.

Sorry I was not able to take your email last week. I was not in the office. I am very sorry that the two anti-ESAM antibodies did not show the staining we had hoped for, it may be that as you say that the epitope presented by the protein (even thou...

Thank you for contacting us. We currently have two antibodies directed towards human EMSA, ab74777 and ab73988. Both are rabbit polyclonals. ab74777 like the antibody you have previously used is directed against the extracellular domain of ESAM...
