Abbreviation: IgA
Target Synonym: Immunoglobulin A;IgA;
Target Species: Human
Usage: This ELISA kit applies to the in vitro quantitative determination of Human IgA concentrations in serum, plasma, saliva, urine.
Tested Sample Types: serum, plasma, saliva, urine
Assay Time: 1.5h
Sensitivity: 0.14 ng/mL
Detection Range: 0.78-50 ng/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 IgA. Samples (or Standards) and Horseradish Peroxidase (HRP) linked antibody specific for Human IgA are added to the micro ELISA plate wells. Human IgA in samples (or standards) combines with the coated antibody and HRP linked detection antibody special to Human IgA.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±2 nm. The OD value is proportional to the concentration of Human IgA. The concentration of Human IgA in the samples is then determined by comparing the OD of the samples to the standard curve.
Cross reactivity: This kit recognizes Human IgA in samples.No significant cross-reactivity or interference between Human IgA and analogues was observed
