An antibody specific for γ-GCS has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyγ-GCS present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for γ-GCS 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 γ-GCS bound in the initial step. The color development is stopped and the intensity of the color is measured.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eProduct Overview\u003c\/b\u003e: Glutamate-cysteine ligase, also known as gamma-glutamylcysteine synthetase, is the first rate limiting enzyme of glutathione synthesis. The enzyme consists of two subunits, a heavy catalytic subunit and a light regulatory subunit. Gamma glutamylcysteine synthetase deficiency has been implicated in some forms of hemolytic anemia.It catalyses the ATP-dependent condensation of cysteine and glutamate to form the dipeptide gamma-glutamylcysteine. The peptide bond in this peptide product is between the carboxylate group of the glutamate and the amino group of the cysteine.The product of the GCL-mediated condensation reaction of L-glutamate and L-cysteine is gamma-glutamylcysteine, which is readily condensed with glycine, by glutathione synthetase, to form glutathione.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eStability\u003c\/b\u003e: 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. \nThe 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).\u003c\/p\u003e","brand":"GeneBio Systems","offers":[{"title":"Default Title","offer_id":47740947660900,"sku":"AE62809HU","price":1037.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0558\/8588\/9636\/files\/no_image_default_image-jpeg_d72a7a00-b3de-4566-9eb3-d69394187331.jpg?v=1768936916","url":"https:\/\/www.genebiosystems.com\/products\/human-gamma-glutamylcysteine-synthetase-g-gcs-elisa-kit","provider":"GeneBio ","version":"1.0","type":"link"}
