The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition.\nTo minimize extra influence on the performance, operation procedures and lab conditions, especially room temperature, air humidity, incubator temperature should be strictly controlled. It is also strongly suggested that the whole assay is performed by the same operator from the beginning to the end.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eAssay procedure summary\u003c\/b\u003e: 1. Prepare all reagents, samples and standards;\n2. Add 50µL standard or sample to each well.\n    And then add 50µL prepared Detection Reagent A immediately.\n    Shake and mix. Incubate 1 hour at 37°C;\n3. Aspirate and wash 3 times;\n4. Add 100µL prepared Detection Reagent B. Incubate 30 minutes at 37°C;\n5. Aspirate and wash 5 times;\n6. Add 90µL Substrate Solution. Incubate 10-20 minutes at 37°C;\n7. Add 50µL Stop Solution. Read at 450 nm immediately.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eTest principle\u003c\/b\u003e: This assay employs the competitive inhibition enzyme immunoassay technique. A monoclonal antibody specific to Quinolinic Acid (QA) has been pre-coated onto a microplate. A competitive inhibition reaction is launched between biotin labeled Quinolinic Acid (QA) and unlabeled Quinolinic Acid (QA) (Standards or samples) with the pre-coated antibody specific to Quinolinic Acid (QA). After incubation the unbound conjugate is washed off. Next, avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. The amount of bound HRP conjugate is reverse proportional to the concentration of Quinolinic Acid (QA) in the sample. After addition of the substrate solution, the intensity of color developed is reverse proportional to the concentration of Quinolinic Acid (QA) in the sample.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eResearch Area\u003c\/b\u003e: -\u003c\/p\u003e\u003cp\u003e\u003cb\u003eReferences Citing This Product\u003c\/b\u003e: \u003ca href=\"https:\/\/www.ncbi.nlm.nih.gov\/pubmed\/27870896\"\u003eM30 Antagonizes Indoleamine 2,3-Dioxygenase Activation and Neurodegeneration Induced by Corticosterone in the Hippocampus.\u003c\/a\u003e\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003ca href=\"https:\/\/www.ncbi.nlm.nih.gov\/pubmed\/28599322\"\u003eMonoamine oxidase A upregulated by chronic intermittent hypoxia activates indoleamine 2, 3-dioxygenase and neurodegeneration\u003c\/a\u003e\u003cp\u003e \u003c\/p\u003e\u003ca href=\"https:\/\/www.ncbi.nlm.nih.gov\/pubmed\/29725904\"\u003eChronic Mild Stress Alters Kynurenine Pathways Changing the Glutamate Neurotransmission in Frontal Cortex of Rats\u003c\/a\u003e\u003cp\u003e \u003c\/p\u003e\u003ca href=\"https:\/\/www.physiology.org\/doi\/abs\/10.1152\/ajpcell.00448.2018\"\u003eExercise training impacts skeletal muscle gene expression related to the kynurenine pathway\u003c\/a\u003e\u003cp\u003e \u003c\/p\u003e\u003ca href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/31727978\/\"\u003eSerotonin is the main tryptophan metabolite associated with psychiatric comorbidity in abstinent cocaine-addicted patients\u003c\/a\u003e\u003cp\u003e \u003c\/p\u003e\u003ca href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/32268268\/\"\u003eKynurenine 3-monooxygenase upregulates pluripotent genes through β-catenin and promotes triple-negative breast cancer progression\u003c\/a\u003e\u003cp\u003e \u003c\/p\u003e","brand":"GeneBio Systems","offers":[{"title":"Default Title","offer_id":48696690081892,"sku":"CEK552Ge","price":1416.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0558\/8588\/9636\/files\/no_image_default_image-jpeg_b554d80c-f6a6-4d72-8314-1c9a9c3effe4.jpg?v=1783134216","url":"https:\/\/www.genebiosystems.com\/en-us\/products\/qa-elisa-kit-for-general-species","provider":"GeneBio ","version":"1.0","type":"link"}
