General Quinolinic Acid (QA) ELISA Kit

• Catalog Number: orb781977
• Category: Assays and Kits
• Description: This assay employs the competitive inhibition enzyme immunoassay technique. The microtiter plate provided in this kit has been pre-coated with Quinolinic Acid(QA) protein. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Quinolinic Acid(QA).
• Reactivity: All
• Concentration: 100 ng/mL
• Tested applications: ELISA
• Application notes: standard: 100 ng/mL. Test principle: This assay employs the competitive inhibition enzyme immunoassay technique. The microtiter plate provided in this kit has been pre-coated with QA protein. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to QA. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of QA in the samples is then determined by comparing the OD of the samples to the standard curve
