Background

xCT, also called SLC7A11, is the light chain component of the cysteine/glutamate amino acid exchange transporter system Xc (1,2). System Xc is composed of two subunits, the light chain (xCT) and the heavy chain (CD98hc, SLC3A2) and functions by cellular uptake of cysteine in exchange for glutamate in a 1:1 ratio (1,2). The human xCT gene is located on chromosome 4q28.3 and is synthesized as a 12-pass transmembrane protein with both the N- and C-terminals located intracellularly (2, 3). xCT is a 501 amino acids (aa) protein with a theoretical molecular weight of 55.4 kDa (3, 4). xCT expression serves many functional purposes in cells including redox balance, ferroptosis, and chemotherapy or cancer drug resistance (1-3, 5-7). Import of cysteine by xCT plays a role in promoting oxidative stress response as cysteine is a precursor for glutathione synthesis (2, 3, 5-7). Glutathione is a cofactor for ROS-detoxifying enzymes, including glutathione peroxidase (GPX), which help defend from cellular ROS-induced damage (2, 3, 5-7). In addition to its antioxidant role, xCT also utilizes glutathione and GPX to inhibit ferroptosis, which is iron-dependent, non-apoptotic cell-death that occurs with overproduction of lipid hydroperoxides (1-3, 5-7). As cancer cells often experience high oxidative stress, it is understandable that xCT is overexpressed in a variety of cancer types, such as acute myeloid leukemia and breast cancer, and affects cancer growth, invasion, metastasis, and prognosis (1-3, 5-7). xCT expression has also been shown to play a role in glutathione-mediated drug resistance during cancer treatment (1,5,7). However, studies have shown that xCT knockdown results in increased tumor cell death, highlighting its suitability as a druggable target (1,5,7). Specifically, the xCT inhibitors Sulfasalazine, an approved anti-inflammatory drug, and Erastin, a small molecule inhibitor, are potential therapeutic modalities for treating a variety of cancers when used in combination with radiotherapy or immunotherapy (1-3, 5-7).

FAQs for xCT Antibody (NB300-318). (Showing 1 - 10 of 10 FAQs).

  1. Do you have a slc7a11 antibody that is conjugated, reacts to mouse, works with cell surface staining, does not need permeabilization?
    • SLC7A11 or xCT antibody NB300-318AF594 targets a cytoplasmic region of the protein, so it should work without permeabilization. However, the data does say it was permeabilized with saponin, so we cannot say for certain if it will work without permeabilization.
  2. I am using the xCT antibody, NB300-318, for IHC. I was wondering if you could recommend a rabbit negative isotype control IGg/serum?
    • I would recommend catalog number NB810-56910 as a rabbit isotype control for NB300-318.
  3. I am using the xCT antibody, NB300-318, for IHC. I was wondering if you could recommend a peptide to use for a negative control?
    • I regret to inform you that we do not have a blocking peptide available for this antibody at this time.
  4. Is there a blocking peptide available for use with NB300-318?
    • We unfortunately do not carry the blocking peptide to NB300-318.
  5. We ordered some xCT antibody (NB300-318). Is itpossible to know if there is -NH2 residues on this synthetic peptide. If so, how many -NH2 or lysine are there?
    • The immunogen for NB300-318 contains 1 lysine residue.
  6. For xCT antibody [NB300-318], why do you see a band at 35kDa when the predicted MW is ~55kDa and xCT is not known to undergo cleavage?
    • Although the theoretical molecular weight of xCT is ~55kDa, the protein’s amino acid structure, with multiple charged residues, results in its fast migration. The research paper by Liefferinge et al 2016 (The Journal of Comparative Neurology 524:1015-1032) shows the testing of several different xCT antibodies in knockout study and it was confirmed that the protein indeed runs at 35kDa (Fig.2. lane 1&2 lanes are xCT positive and lanes 3&4 are from xCT knockouts).  
  7. Hello, I'm trying to run a western blot with NB300-318. What is the blocking buffer used?
    • For NB300-318 we recommend using 5% milk to block Blocking solution 1X TBST 5% non-fat dry milk
  8. Is NB300-318 suitable for live cell flow cytometry? (is its epitope in the external side of the cells?) I would need it for FACS sorting application
    • The immunogen for this antibody is cytoplamic, so this antibody would not be suitable for live flow.
  9. I am using the xCT antibody NB300-318 for IHC.  I was wondering if you could recommend  a rabbit negative isotype control IGg/serum?
    •  I would recommend NB810-56910 as an isotype control for you
  10. We are wondering if it is possible to know if there is -NH2 residues on this synthetic peptide. If yes, how many -NH2 or lysine are there?
    • The immunogen for NB300-318 contains 1 lysine residue.
