| Product Name | Chemiluminescence Immunoassay Reaction Matrix Diluent |
| Catalog No. | ATRD-0016 |
| Description | A protein-containing diluent matrix formulated for the dilution of serum and plasma samples in chemiluminescence immunoassay systems. The diluent contains a balanced mixture of animal-derived and recombinant proteins to minimize matrix effects, reduce non-specific binding, and maintain antigen stability during automated processing. It is specifically optimized for sandwich immunoassay formats where low background signal and linear dilution recovery are critical performance parameters. |
| Intended Use | Dilution of serum and plasma specimens for chemiluminescence immunoassay testing to reduce matrix interference. |
| Principle / Technology | Protein-supplemented buffer matrix providing carrier protein protection and non-specific binding suppression |
| Detection Method | Chemiluminescence (various analyzer platforms) |
| Sample Type | Human serum, EDTA plasma, lithium heparin plasma |
| Performance Range / Specifications | Dilution recovery: 90–110% across 1:2 to 1:100 dilution range for most analytes |
| Sensitivity / LOD | Background signal ≤0.1% of calibrator high signal in blank diluent wells |
| Specificity | Broad compatibility with sandwich immunoassay formats across multiple analyte panels |
| Reaction Conditions / Protocol | Use undiluted for manual or automated sample dilution; typical dilution ratios 1:2 to 1:100 |
| Components / Formulation | PBS-based buffer with BSA (1%), casein (0.5%), non-ionic surfactant, ProClin preservative |
| Storage Conditions | 2–8 °C; stable for 30 days after opening with aseptic handling |
| Shelf Life | 18 months at 2–8 °C |
| Package Specifications | 100 mL, 500 mL |
| Product Form | Liquid, ready-to-use |
| Quality Control | Lot release testing includes linearity verification with multiplexed calibrator panel; endotoxin ≤0.5 EU/mL |
| Key Features | Multi-protein formulation provides robust matrix compensation across patient populations with varying endogenous protein profiles |
| Purity | Endotoxin ≤0.5 EU/mL; sterile-filtered; protein and preservative content as specified |
| Concentration | Ready-to-use; no dilution required |
| Activity / Unit Definition | Dilution linearity R² ≥0.99 across specified range |
| Molecular Weight | Not applicable — buffered protein solution |
| Source / Origin | Bovine serum albumin, casein, and synthetic buffer components |
| pH Range / Optimal pH | pH 7.2–7.6 |
| Shipping Conditions | Ambient temperature with cold packs for summer months |
| Expiration Date / Stability | 12–18 months at 2–8 °C |
| Regulatory / Compliance | For IVD use; manufactured under ISO 13485 quality system |
| Compatibility | Compatible with ELISA, CLIA, and immunoturbidimetric assay platforms |
| Recommended Buffer System | PBS-based with protein stabilizers and antimicrobial preservative |
| Application Notes / Precautions | Bring to room temperature before use; avoid repeated freeze-thaw; use aseptic technique for opened bottles |
| Batch-to-Batch Consistency | Dilution recovery 90–110% for reference analyte panel per lot |
For research use only, not for clinical use.
