Test Principale: This assay employs a two-site sandwich ELISA to quantitate SLC7A11 in samples. An antibody specific for SLC7A11 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anySLC7A11 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for SLC7A11 is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of SLC7A11 bound in the initial step. The color development is stopped and the intensity of the color is measured.

Product Overview: SLC7A11 is a member of a heteromeric Na (+) -independent anionic amino acid transport system highly specific for cystine and glutamate. In this system, designated system Xc (-), the anionic form of cystine is transported in exchange for glutamate. The deduced 502-amino acid protein had an apparent molecular mass of about 40 kD following in vitro translation in canine pancreatic microsomes. Mouse xCT was found to be extremely hydrophobic and was predicted to contain 12 membrane-spanning domains. Northern blot analysis of activated mouse macrophages detected transcripts of 12, 3.5, and 2.5 kb. Northern blot analysis of mouse tissues detected expression in brain, but not in other organs tested. The 501-amino acid XCT protein has 12 transmembrane domains and cytoplasmic N and C termini.

Stability: The stability of ELISA kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition. The loss rate was determined by accelerated thermal degradation test. Keep the kit at 37°C for 4 and 7 days, and compare O.D.values of the kit kept at 37°C with that of at recommended temperature. (referring from China Biological Products Standard, which was calculated by the Arrhenius equation. For ELISA kit, 4 days storage at 37°C can be considered as 6 months at 2 - 8°C, which means 7 days at 37°C equaling 12 months at 2 - 8°C) .
