Manufacturing Science¶
Manufacturing a fluorescence immunochromatographic test strip is a materials-science and bioconjugation problem, not just an assembly task. This section documents the scientific principles that govern Migibio's production process and explain why the resulting assays perform consistently.
What Determines Assay Performance at the Manufacturing Level¶
| Layer | Scientific determinant | Impact on result |
|---|---|---|
| Conjugation | Antibody–fluorophore coupling efficiency & ratio | Signal intensity, sensitivity |
| Membrane coating | Dispense uniformity, line geometry | Precision (CV%), linearity |
| Drying | Temperature/humidity kinetics | Background, antibody activity |
| Lamination | Capillary continuity | Flow reliability |
Each of these is a controllable, measurable process parameter — not a black box.
Why Manufacturing Science Matters to the Customer¶
- Reproducibility: a well-characterized process produces the same result in lot N+1 as in lot N.
- Traceability of claims: every performance claim (LOD, CV%) is a property of a manufactured product, reproducible only because the process is controlled.
- OEM confidence: for OEM/ODM partners, a documented manufacturing science means a reliable product under their brand.
