xCT Antibodies
xCT is the light chain component of the cysteine/glutamate amino acid exchange transporter system xC. It is synthesized as a 12-pass transmembrane protein with a theoretical molecular weight of 55.4 kDa. xCT expression serves many functional purposes in cells including redox balance, ferroptosis, and drug resistance. We offer multiple well-reviewed antibodies to detect xCT that have been cited in 60+ publications. Browse our catalog of polyclonal and xCT-conjugated antibodies. Our xCT antibodies have been validated for multiple research applications including Dual RNAscope ISH-IHC, Flow Cytometry, Immunoblotting, ICC, Immunofluorescence, IHC-Frozen, IHC-Paraffin, Immunoprecipitation (Negative), Simple Western, and Western Blot. These cXT antibodies are suitable in Human, Mouse, and Rat species. Use the list below to choose the anti-xCT antibody which is most appropriate for your research; you can click on each one to view full technical details, images, references, reviews, and related products. Each xCT antibody is fully covered by Novus’ Guarantee+ to give you peace of mind and support when you need it.
