| Product Name | Serum/Plasma Sample Diluent, Universal |
| Catalog No. | ATRD-0001 |
| Description | A universal sample dilution matrix formulated to closely mimic the ionic strength and protein composition of human serum and plasma, enabling accurate dilution of clinical specimens for immunoassay measurement. |
| Intended Use | Dilution of human serum, plasma, and other biological fluid specimens prior to analysis by ELISA, chemiluminescent immunoassay, and multiplex bead-based immunoassay platforms. |
| Principle / Technology | Bovine serum albumin and other carrier proteins in a buffered saline matrix normalize protein concentration and minimize non-specific binding differences between diluted samples. |
| Detection Method | Parallelism testing with serial dilutions of clinical samples, spike recovery assessment |
| Sample Type | Human serum, EDTA plasma, heparin plasma, citrate plasma |
| Performance Range / Specifications | Parallelism 85–115% across 4-fold dilution range; spike recovery 90–110% |
| Sensitivity / LOD | N/A |
| Specificity | Matrix compatible with >95% of commercial sandwich ELISA kits |
| Reaction Conditions / Protocol | Use undiluted; dilute samples in polypropylene tubes to minimize protein adsorption to tube walls; mix gently by inversion. |
| Components / Formulation | Tris-buffered saline pH 7.4, bovine serum albumin, non-ionic surfactant, ProClin 300 preservative |
| Storage Conditions | 2–8°C |
| Shelf Life | 18 months |
| Package Specifications | 100 mL, 500 mL |
| Product Form | Liquid, ready to use |
| Quality Control | Parallelism validation against 10 clinical serum samples, preservative efficacy testing |
| Key Features | Matrix-matched to clinical samples; ready to use; broad immunoassay compatibility; low lot-to-lot variability |
For research use only, not for clinical use.
