Lablisa® Human BMG/β2-MG(Beta-2-Microglobulin) ELISA Kit
Catalog No.: LAB11071
| Reactivity | Human |
| Detection Range | 31.25-2000ng/mL |
| Sensitivity | 18.75ng/mL |
Description
This ELISA kit uses the Competitive-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.

Precision
Intra-assay Precision (Precision within an assay) ：CV%<8% Three samples of known concentration were tested twenty times on one plate to assess intra-assay precision.
Inter-assay Precision (Precision between assays) ：CV%<10% Three samples of known concentration were tested in forty separate assays to assess inter-assay precision.
Recovery
Matrices listed below were spiked with certain level of recombinant Human BMG/β2-MG and the recovery rates were calculated by comparing the measured value to the expected amount of Human BMG/β2-MG in samples.
| Matrix | Recovery range | Average |
|---|---|---|
| serum (n=8) | 87-95% | 92% |
| EDTA plasma (n=8) | 97-103% | 100% |
| Cell culture media (n=8) | 94-102% | 98% |
Linearity
The linearity of the kit was assayed by testing samples spiked with appropriate concentration of Human BMG/β2-MG and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.
| Matrix | 1:2 | 1:4 | 1:8 | 1:16 |
|---|---|---|---|---|
| serum (n=8) | 92-99% | 99-106% | 93-101% | 99-107% |
| EDTA plasma (n=8) | 96-103% | 87-96% | 87-96% | 92-100% |
| Cell culture media (n=8) | 90-98% | 89-97% | 95-105% | 94-102% |
