“Quanticon” Human BMG/β2-MG(Beta-2 Microglobulin) ELISA Kit

Principle

This ELISA kit uses the Sandwich ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with Human BMG/β2-MG. During the reaction, Human BMG/β2-MG in the sample or standard competes with a fixed amount of Human BMG/β2-MG on the solid phase supporter for sites on the Biotinylated Detection Ab specific to Human BMG/β2-MG. Excess conjugate and unbound sample or standard are washed away, and Avidin-Horseradish Peroxidase (HRP) conjugate are added to each micro plate well and incubated. Then a TMB substrate solution is added to each well. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns from blue to yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm. The concentration of Human BMG/β2-MG in tested samples can be calculated by comparing the OD of the samples to the standard curve

Specification

Precision

Mean coefficient of variation for Intra-Assay and Inter-Assay: 3 samples with low, middle and high level concentration were tested for repeat multiple times, respectively.

Rate of recovery

Three matrices listed below were spiked with certain level of Human BMG/β2-MG, The recovery rates of Human BMG/β2-MG were calculated by comparing the measured value to the expected amount of Human BMG/β2-MG in samples
