Our Abpromise guarantee covers the use of ab37185 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
WB Use a concentration of 0.5 - 2 µg/ml. Predicted molecular weight: 55 kDa.

xCT forms heterodimer with 4F2Hc protein hence reducing conditions should be used in WB. It exists as multi-pass membrane protein therefore we recommend heating the lysates for 15-20 minutes at 60-70C.

Flow Cyt Use a concentration of 2 - 3 µg/ml.

ab171870 - Rabbit polyclonal IgG, is suitable for use as an isotype control with this antibody.

IHC-P Use a concentration of 5 µg/ml.
ICC/IF 1/100 - 1/1000.
IHC-FoFr Use at an assay dependent concentration. PubMed: 21639880

  • All lanes : Anti-xCT antibody (ab37185) at 0.5 µg/ml

    Lane 1 : Total human stomach lysate.
    Lane 2 : Total mouse stomach lysate.

    Lysates/proteins at 50 µg per lane.

    Developed using the ECL technique.

    Predicted band size: 55 kDa
    Observed band size: 55 kDa

  • Imunocytochemistry/ Immunofluorescence analysis of HepG2 cells labeling xCT with ab37185 followed by Dylight 488 (green). Nuclei and alpha-tubulin were counterstained with DAPI (blue) and Dylight 550 (red) respectively. 

  • Immunohistochemical analysis of small intestine labeling xCT with ab37185. Staining is observed in the absorptive epithelia of small intestinal villi. 

  • PFA perfusion fixed frozen sections of spinal cord of control (left) and MS patients (right) stained for xCT using ab37185 at 5 µg/ml.
