Description

General description

Latex bead suspensions mostly contain polymer particles and water. It includes small amounts of surfactant, sodium bicarbonate, and potassium sulfate. Polystyrene microparticles are stabilized colloidal particles bearing a negative charge. Polymerization of styrene under certain conditions results in spontaneous coalescent bead formation leading to the formation of microparticles.

Application

Latex beads, polystyrene have been used:

• in phagocytosis experiments
• to provide a stimulated condition for adjusting the neutrophil count in cell suspension
• to incubate macrophages for phagosome trafficking assays

Biochem/physiol Actions

Latex beads (polystyrene) are used in electron microscopy, cell counter calibration, antibody-mediated and agglutination diagnostics.
