QuicKey Pro Human CA19-9 (Carbohydrate antigen19-9) ELISA Kit

Storage: 2-8°C，6 months

Target Synonym: sialylated Lewis(a) Antigen;Cancer Antigen 19-9

Usage: This ELISA kit applies to the in vitro quantitative determination of Human CA19-9 concentrations in serum, plasma and other biological fluids.

Tested Sample Types: Serum, plasma and other biological fluids

Type: Sandwich-ELISA

Assay Time: 1 h 30 min

Detection Type: Colorimetric method;ELISA;Sandwich

Sensitivity: 3.75 U/mL

Detection Range: 6.25-400 U/mL

Test Principle: This ELISA kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Human CA19-9. Samples (or Standards) and Horseradish Peroxidase (HRP) linked antibody specific for Human CA19-9 are added to the micro ELISA plate wells. Human CA19-9 in samples (or standards) combines with the coated antibody and HRP linked detection antibody special to Human CA19-9.Excess conjugate and unbound sample or standard are washed from the plate. The substrate solution is added to each well. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of Human CA19-9. The concentration of Human CA19-9 in the samples is then determined by comparing the OD of the samples to the standard curve.
