Human Carbohydrate Antigen 19-5 (CA19-5) ELISA Kit

• Catalog Number: orb780925
• 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 Carbohydrate Antigen 19-5(CA19-5) protein. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Carbohydrate Antigen 19-5(CA19-5).
• Reactivity: Human
• Concentration: 200 ng/mL
• Tested applications: ELISA
• Application notes: standard: 200 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 Human CA19-5 protein. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human CA19-5. 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 Human CA19-5 in the samples is then determined by comparing the OD of the samples to the standard curve
