  • ab112997 at 1ug/ml staining Transketolase in HL60 cells by Flow Cytometry (blue). Isotype control antibody (red).
  • ab112997 at 1ug/ml staining Transketolase in HeLa cells by Immunocytochemistry (4% paraformaldehyde fixed and 0.1% Triton X-100 permeabilized) followed by Alexa Fluor® 594 goat anti-mouse IgG (H+L) used at a 1/1000 dilution for 1 hour (red). Nuclei were stained with DAPI (blue). Non specific fluorescence was reduced using a signal enhancer.
  • IHC image of Transketolase staining in Human normal colon formalin fixed paraffin embedded tissue section, performed on a Leica BondTM 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 ab112997, 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.

Customer reviews and Q&As

Thank you very much for your interest in Abcam products.

To our knowledge, ab112997 has not been tested in Dog. However the immunogen sequence of ab112997 is quite homologous with Dog species so this ab most likely would cross react. I would e...

Thank you for contacting Abcam regarding ab112997.

Our TKT antibody was developed from a shotgun project, thus we do not exactly know the epitope of the antibody. The antibody was validated with Hela cells which express both TKT and TKT...
