| Product Name | 0.05-20 µm Carboxyl Fluorescent Polystyrene Microspheres with 460-750 nm Emission |
| Catalog No. | IGM-HMM-0267 |
| Description | Alta DiagnoTech fluorescent polystyrene microspheres contain bright dyes embedded within monodisperse beads. Internal staining reduces quenching and environmental effects while preserving carboxyl groups for surface coupling in assay and research workflows. |
| Intended Use | Lateral-flow assays, phagocytosis studies, pore-size measurement, biochips, microfluidics and other fluorescence-based research applications. |
| Principle / Technology | Internally embedded fluorescent dyes in carboxyl-functionalized polystyrene microspheres. |
| Detection Method | Fluorescence detection |
| Performance Range / Specifications | Particle-size range 0.05-20 µm; 1.0% w/v solids; visible emission coverage 460-750 nm. Listed excitation/emission pairs include 430/460, 495/515, 550/570, 560/605, 625/640 and 660/680 nm; the product table also lists 540 and 680 nm emission options. |
