SpecificityThis kit recognizes natural and recombinant Abeta42. No significant cross-reactivity or interference between Abeta42 and analogues was observed.
SamplesSerum, plasma and other biological fluids.
Product Description specificalIntended Uses: This CLIA kit applies to the in vitro quantitative determination of Abeta42 concentrations in serum, plasma and other biological fluids.
Principle of the Assay||This kit uses Sandwich-CLIA as the method. The micro CLIA plate provided in this kit has been pre-coated with an antibody specific to Abeta42. Standards or samples are added to the appropriate micro CLIA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Abeta42 and Avidin-Horseradish Peroxidase (HRP) conjugate is added to each micro plate well successively and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Abeta42, biotinylated detection antibody and Avidin-HRP conjugate will appear fluorescence. The Relative light unit (RLU) value is measured spectrophotometrically by the Chemiluminescence immunoassay analyzer. The RLU value is positively associated with the concentration of Abeta42. You can calculate the concentration of Abeta42 in the samples by comparing the RLU value of the samples to the standard curve.
