| Product Name | Beta-2-Microglobulin CLIA Kit |
| Catalog No. | TMTR-HMM-0065 |
| Description | A chemiluminescence immunoassay for the quantitative determination of beta-2-microglobulin in serum and urine, serving as a prognostic marker for hematological malignancies and an indicator of renal tubular function. |
| Intended Use | Quantitative B2M measurement in serum for multiple myeloma and CLL prognosis, and in urine for renal tubular function assessment. |
| Principle / Technology | Competitive CLIA format with acridinium ester-labeled B2M tracer competing with sample B2M for monoclonal antibody binding sites. |
| Detection Method | Automated chemiluminescence detection |
| Sample Type | Human serum and urine; urine specimens require adjustment to pH 6.0–8.0 prior to testing |
| Performance Range / Specifications | Serum: 0.1–50 mg/L; Urine: 0.01–5 mg/L |
| Sensitivity / LOD | Serum: ≤0.05 mg/L; Urine: ≤0.005 mg/L |
| Specificity | Specific for human B2M; no cross-reactivity with MHC class I heavy chain or other low-molecular-weight proteins |
| Reaction Conditions / Protocol | 20-minute competitive incubation followed by separation, wash, and signal measurement |
| Components / Formulation | Anti-B2M antibody reagent, acridinium ester-B2M conjugate, assay buffer, serum calibrator set, urine calibrator set, quality controls |
| Storage Conditions | 2–8°C; dedicated calibrator sets for serum and urine matrices |
| Shelf Life | 18 months |
| Package Specifications | 100 tests |
| Product Form | Ready-to-use liquid reagents |
| Quality Control | Calibrator values assigned by weight; separate serum and urine control materials; inter-assay CV below 5% |
| Key Features | Dual sample type capability with matrix-matched calibrators; competitive format provides robust and interference-resistant performance; accepted hematological malignancy staging marker per international guidelines |
For research use only, not for clinical use.
