  • Experimental Validation Results for xCT Antibody (YA652)
    Western blot analysis of extracts from HT-29(lane 2(20ug) , A549(lane 3(20ug) and HCT116(lane 4(20ug) using xCT Antibody (HY-P80523) Mouse mAb. Proteins were transferred to a PVDF membrane and blocked with 5% non-fat milk in TBST for 2 hour at room temperature. The primary antibody (1/1000) and Loading control antibody (Beta Actin, HY-P83730, 1/10000) was used in 5% non-fat milk in TBST at 4°C overnight. Goat Anti-Mouse/Rabbit IgG-HRP Secondary Antibody (1/10000) was used for 1 hour at room temperature.
  • Experimental Validation Results for xCT Antibody (YA652)
    Immunohistochemical analysis of paraffin-embedded mouse testis tissue using xCT Antibody. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH 6.0) for 8 minutes. The tissues were blocked in QuickBlock for 20 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibody at 1/100 dilution in 4℃ overnight. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.

    Flow cytometric analysis of 1.5X10^6 U937 cells labeling xCT Antibody (YA652) (HY-P80523, red). Cells were fixed with 4% paraformaldehyde. Then stained with the primary antibody at 1/200 dilution for an hour at 4℃. Goat Anti-Rabbit IgG H&L (AF488) (HY-P8002) was used as the secondary antibody at 1/1,000 dilution for 30 minutes at 4℃. Rabbit IgG Isotype Control (HY-P80879, blue) was used as the isotype control, cells without incubation with primary antibody were used as the unlabeled control (black).

Cells were fixed in 4% paraformaldehyde for 15 minutes at room temperature, permeabilized with 0.1% Triton X-100 in PBS for 15 minutes at room temperature, then blocked with quick block buffer for 10 minutes at room temperature. Cells were then incubated with xCT Antibody (HY-P80523) at 1/100 dilution in quick block buffer overnight at 4 ℃. AF488-conjugated Goat Anti-Mouse IgG H&L(HY-P8005, Green) was used as the secondary antibody at 1/1,000 dilution. PBS instead of the primary antibody was used as the secondary antibody only control. The Nuclear counterstain was DAPI (Blue).

Background

  • Function

    xCT is a Heterodimer with SLC3A2, that functions as an antiporter by mediating the exchange of extracellular anionic L-cystine and intracellular L-glutamate across the cellular plasma membrane. Provides L-cystine for the maintenance of the redox balance between extracellular L-cystine and L-cysteine and for the maintenance of the intracellular levels of glutathione that is essential for cells protection from oxidative stress. The transport is sodium-independent, electroneutral with a stoichiometry of 1:1, and is drove by the high intracellular concentration of L-glutamate and the intracellular reduction of L-cystine. In addition, mediates the import of L-kynurenine leading to anti-ferroptotic signaling propagation required to maintain L-cystine and glutathione homeostasis. Moreover, mediates N-acetyl-L-cysteine uptake into the placenta leading to subsequently down-regulation of pathways associated with oxidative stress, inflammation and apoptosis. In vitro can also transport L-aspartate. May participate in astrocyte and meningeal cell proliferation during development and can provide neuroprotection by promoting glutathione synthesis and delivery from non-neuronal cells such as astrocytes and meningeal cells to immature neurons. Controls the production of pheomelanin pigment directly[1][2][3][4][5][6][7][8].
