| Product Name | Immunoassay Analyzer Probe Wash Solution, Ready-to-Use |
| Catalog No. | ATRCS-0014 |
| Description | A ready-to-use aqueous cleaning solution designed for sample and reagent probe washing in automated immunoassay analyzers. The formulation combines a proteolytic enzyme component with non-ionic detergents to digest and remove protein residues from probe surfaces. This dual-action mechanism prevents cross-contamination and maintains probe dispensing accuracy without the corrosive effects associated with strong acid or alkaline cleaners. |
| Intended Use | Enzymatic cleaning of immunoassay analyzer sample and reagent probes to prevent protein buildup and cross-contamination. |
| Principle / Technology | Proteolytic enzyme digestion combined with mild detergent surface cleaning |
| Detection Method | Instrument carryover verification by running blank samples after high-concentration calibrators |
| Sample Type | Sample probes, reagent probes, and mixing paddles in automated chemiluminescence and ELISA analyzer platforms |
| Performance Range / Specifications | Carryover rate: ≤0.1 μg/dL after cleaning cycle as verified by serial high-low sample testing |
| Sensitivity / LOD | Removes ≥99% of adsorbed protein from probe surfaces within the instrument wash cycle time |
| Specificity | Enzymatic protease targets protein residues; mild formulation safe for stainless steel, PEEK, and Teflon probe materials |
| Reaction Conditions / Protocol | Load directly into instrument wash solution reservoir; instrument software controls wash frequency and volume |
| Components / Formulation | Protease enzyme solution with non-ionic detergent, pH-neutral buffer, and preservative |
| Storage Conditions | 2–8 °C; bring to room temperature before loading on instrument |
| Shelf Life | 12 months at 2–8 °C; 30 days after opening |
| Package Specifications | 1 L bottle |
| Product Form | Liquid, ready-to-use |
| Quality Control | Protein removal efficacy verified by BCA assay of probe rinse solution after cleaning a BSA-contaminated probe |
| Key Features | Enzymatic mode of action eliminates corrosive effects on sensitive instrument fluidic components |
| Purity | Free of particulate; filtered; residue-free evaporation |
| Concentration | As specified (concentrate or ready-to-use) |
| Activity / Unit Definition | Cleaning efficacy validated by instrument carryover testing |
| Molecular Weight | Not applicable — detergent/surfactant formulations |
| Source / Origin | Synthetic detergent and surfactant components |
| pH Range / Optimal pH | Alkaline pH 10–13 or acidic pH 2–4 depending on formulation |
| Shipping Conditions | Ambient temperature; avoid freezing for liquid formulations |
| Expiration Date / Stability | 24 months in unopened container |
| Regulatory / Compliance | For IVD instrument maintenance; CE-marked components available |
| Compatibility | Compatible with specified automated analyzer systems; material compatibility verified |
| Recommended Buffer System | Use undiluted or dilute per instrument manufacturer specification |
| Application Notes / Precautions | Avoid skin and eye contact; use appropriate PPE; rinse instrument thoroughly after cleaning cycle |
| Batch-to-Batch Consistency | pH and conductivity within ±5% of reference lot; cleaning efficacy validated |
