Background Information

SLC7A11 (also known as xCT) is a membrane transporter involved in the uptake of cystine. It promotes glutathione synthesis through the uptake of cystine and the concomitant release of glutamate. This, in turn, protects cells from oxidative stress, maintains cellular redox balance, and prevents cell death induced by lipid peroxidation. SLC7A11 has been identified as a potential target for cancer therapeutics. It is overexpressed in multiple malignant tumors and is closely associated with the growth, prognosis, metastasis, and treatment response of various cancers including lung cancer. 26864-1-AP recognizes the 55 kDa and 35-40 kDa protein similar to the paper published (PMID: 32188872, 19156441).

Melanie (Verified Customer) (05-11-2022)

Tested the antibody in Hek293T cells. Had to dilute the antibody 1:50000, since the signal was to strong. Very clear gang at the calculated MW. Good antibody!

Amélie (Verified Customer) (05-03-2022)

We used the AB on Bone Marrow derived Macrophages, where Slc7a11 is KO (validate by RT PCR), in Western blot. We did not found a specific staining in the right size.

• Applications: Western Blot
• Primary Antibody Dilution: 1000
• Cell Tissue Type: Bone Marrow derived macrophages from WT or KO mice
