  • Application notes
    Is unsuitable for ICC or IP.
  • Target

    • Function

      Has a pivotal role in cytoprotective cellular mechanisms triggered by oxygen deprivation. May play a role as a molecular chaperone and participate in protein folding.
    • Tissue specificity

      Highly expressed in tissues that contain well-developed endoplasmic reticulum and synthesize large amounts of secretory proteins. Highly expressed in liver and pancreas and lower expression in brain and kidney. Also expressed in macrophages within aortic atherosclerotic plaques, and in breast cancers.
    • Sequence similarities

      Belongs to the heat shock protein 70 family.
    • Cellular localization

      Endoplasmic reticulum lumen.

    • Overlay histogram showing HepG2 cells stained with ab124884 (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 (ab124884, 1/1000 dilution) for 30 min at 22°C. The secondary antibody used was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) (ab150077) at 1/2000 dilution for 30 min at 22°C. Isotype control antibody (black line) was rabbit IgG (monoclonal) (0.1μg/1x106 cells) used under the same conditions. Unlabelled sample (blue line) was also used as a control. Acquisition of >5,000 events were collected using a 20mW Argon ion laser (488nm) and 525/30 bandpass filter. This antibody gave a positive signal in HepG2 cells fixed with 4% paraformaldehyde (10 min)/permeabilized with 0.1% PBS-Tween for 20 min used under the same conditions.

    Thank you for taking the time to complete our questionnaire. I am sorry to hear you have had difficulty obtaining satisfactory results from this antibody.

    The details you have kindly provided will enable us to investigate this case for you and this is also helpful in our records for monitoring of quality.

    I can confirmthat this antibody was ordered in march and therefore iscovered by ourAbpromise guarantee.

    Reviewing this case, I would like to offer some suggestions to help optimise the results from ab124884.

    1.) All the suggestions form my last email:

    As a first troubleshooting tips I would like to suggest to review the protease inhibitors used since all extra bands are smaller than the target protein. They could be degradation products.

    I also suggest to run a no primary control to exclude the possibility that
    the secondary is producing the multiple extra bands.

    Since cell line that have been in culture for a long time can sometimes deliver unforeseen results, I suggest to use liver lysate as a positive control or a different cell line like HeLa or MCF7.

    2.) To achieve the most specific binding I recommend to incubate the primary antibody over night at 4C.

    3.) Some antibodies give better results when BSA is used as blocking agent. I can recommend to use 5% in the blocking buffer and to use 1% in the antibody solutions.

    I hope this information is helpful, thank you for your cooperation. Should the suggestions not improve the results, please do not hesitate to contact me again with the further requested details.
