Our Abpromise guarantee covers the use of ab91293 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
ELISA 1/1000.
IHC-P Use a concentration of 5 µg/ml. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
WB 1/100 - 1/500. Predicted molecular weight: 18 kDa.



  • IHC image of RPS18 staining in Human normal liver formalin fixed paraffin embedded tissue section, performed on a Leica Bond™ 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 ab91293, 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.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

Thank you for your enquiry and interest.
This customer seems to be interested in testing ab91293 in a new application (IP) and in a new species (rabbit). Even though the homology of the rabbit RPS18 to human is 100%, it is not been properly tested yet. This means that two unknown factors would be introduced into the experimental system. In order to be able to interpret the results correctly, it would be very important to apply a good positive control sample (mouse or human spleen or GI tract tissue lysates). I hope your customer can understand our policy. Please do let me know if the recommendation can be accepted and followed.
I look forward to hearing from you soon.

Thank you for contacting Abcam.

Since you are experiencing trouble with GAPHDand alpha-tubulin antibodies, then I would suggest that you try the mitochondrial antibody marker, ab122278, as tubulin is cytosolic but that does not seem to be working for you. However I do suggest that you also consult the latest literature and to see how others in the field are dealing with this issue.

If there is anything else I can help you with, please let me know.
