Lablisa® Human HMGB-1(HighMobility Group Protein B1) ELISA Kit
Product Information
- Description
- More Infomation
The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human HMGB-1. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human HMGB-1. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Human HMGB-1, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Human HMGB-1 in the samples is then determined 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 HMGB-1 and the recovery rates were calculated by comparing the measured value to the expected amount of HMGB-1 in samples.
| Matrix | Recovery range | Average |
|---|---|---|
| serum(n=5) | 80-97% | 88% |
| EDTA plasma(n=5) | 85-101% | 93% |
| Heparin plasma(n=5) | 83-97% | 90% |
Linearity
The linearity of the kit was assayed by testing samples spiked with appropriate concentration of HMGB-1 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=5) | 91-99% | 83-89% | 88-104% | 97-103% |
| EDTA plasma(n=5) | 85-104% | 83-96% | 95-103% | 88-95% |
| Heparin plasma(n=5) | 86-93% | 93-101% | 86-97% | 90-101% |
