Anti-Egr1 antibody [mAbcam55160] images

  • Egr1 was immunoprecipitated using 0.5mg Hela whole cell extract, 5µg of Rabbit polyclonal to Egr1 and 50µl of protein G magnetic beads (+). No antibody was added to the control (-).

    The antibody was incubated under agitation with Protein G beads for 10min, Hela whole cell extract lysate diluted in RIPA buffer was added to each sample and incubated for a further 10min under agitation.

    Proteins were eluted by addition of 40µl SDS loading buffer and incubated for 10min at 70°C; 10µl of each sample was separated on a SDS PAGE gel, transferred to a nitrocellulose membrane, blocked with 5% BSA and probed with ab55160.

    Secondary: Mouse monoclonal [SB62a] Secondary Antibody to Rabbit IgG light chain (HRP) (ab99697).

    Band: 55kDa; Egr1

  • All lanes : Anti-Egr1 antibody [mAbcam55160] (ab55160) at 5 µg/ml

    Lane 1 : HeLa (Human epithelial carcinoma cell line) Whole Cell Lysate
    Lane 2 : HeLa (Human epithelial carcinoma cell line) Nuclear Lysate - TPA stimulated 2 hr (ab14653)

    Lysates/proteins at 20 µg per lane.

    Goat polyclonal to Mouse IgG - H&L - Pre-Adsorbed (HRP) at 1/3000 dilution

    Performed under reducing conditions.

    Predicted band size : 58 kDa
    Observed band size : 55,85 kDa (why is the actual band size different from the predicted?)
  • ab55160 (1/250) staining Egr1 in paraffin-embedded Human placenta tissue.  Tissue underwent fixation in formaldehyde, peroxidase blocking, protein blocking and heat mediated antigen retrieval.  The secondary antibody was goat anti rabbit/mouse conjugated to HRP.  For further experimental details please refer to abreview.

  • Overlay histogram showing HeLa cells stained with ab55160 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab55160, 1µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG2a [ICIGG2A] (ab91361, 1µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed.
