Latex beads, amine-modified polystyrene, fluorescent red (this product) are supplied as a 2.5% aqueous suspension. The exact particle concentration (number of beads per mL) is not included in the official product specification and is not routinely measured during quality control testing. However, for general reference, the 2.5% suspension typically contains approximately 4.57 × 10¹⁰ particles per mL. This value is an estimate and may vary between lots. For applications requiring precise particle counts, determining the concentration experimentally using appropriate analytical methods is recommended.

Application
Latex beads, amine-modified polystyrene, fluorescent red has been used:
- to study the effect of Ganoderma lucidum polysaccharides (GLP) on microglia phagocytic behavior[1]
- to study cell phagocytosis in human leukemia cell lines[2]
- in macrophage phagocytosis assay[3]
- to induce detectable engulfment by microglia in Ganoderma lucidum[1]
Biochem/physiol Actions
Amine-modified polystyrene latex beads have been used to develop an electrochemical nitrite nanosensor as well as to validate a pharyngeal aspiration technique for exposing the mouse lung to respirable particles.
