  • TOMM22 antibody (ab57523) used in immunohistochemistry at 3ug/ml on formalin fixed and paraffin embedded human small Intestine.
  • TOMM22 antibody (ab57523) at 1ug/lane + NIH/3T3 cell lysate at 25ug/lane.
  • ICC/IF image of ab57523 stained HeLa cells. The cells were 4% formaldehyde 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 (ab57523, 10µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-mouse 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.

  • Overlay histogram showing HeLa cells stained with ab57523 (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 (ab57523, 1µg/1x106 cells) for 30 min at 22°C. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22°C. 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.

We also do recommend using RIPA buffer rather than NP40 for mitochondrial targets, would this be something you are able to do with your samples?

Thank you very much for your patience while I was in discussion with lab.

My colleague has confirmed that, they tested ab57523 with PC-12, Raw 264.7 and NIH/3T3 cells in western blot and they haven't observed any band at 88kDa. The band they o...

Thank you for providing this extra information. The alignment shows a very low homology between the yeast protein and the human TOMM2 protein (www.uniprot.org/uniprot/Q9NS69), 16% only. This result suggests that unfortunately the TOMM2 ...

Thank you very much for your inquiry. Unfortunately we do not have an antibody in our catalogue for the moment for which we can suggest a crossreactivity with the yeast SEC61 proteins. I am very sorry for this. Please see further below for the alignmen...
