General description

Polystyrene microparticles are anionic-stabilizedcolloidal particles. These microparticles are synthesized by the polymerizationof styrene under conditions that produce coalescent bead formation. Polystyrenelatex beads have a wide range of applications including phagocytosis experiments,antibody-mediated agglutination diagnostics, electron microscopy, and cellcounter calibration.

Application

Polystyrene latex beads have been used:
  • inthe flow cytometric assay of endothelial microparticles (EMPs)[1]
  • in thedetection of capsular polysaccharide (CPS) antibody/antigen latex agglutinationtest[2]
  • to evaluate the phagocytic activity in hemocytes of shrimps[3]

Questions

1–4 of 4 Questions  
  1. If I would like to dilute the concentration of this solution, what solvent can I dilute it with?

    1 answer
    1. These particles may be diluted using deionized water. Note that very dilute preparations may cause the particles to clump or flocculate. The additional of Triton X- 100, SDS, or TWEEN 20 at a range of 0.01-0.1% may be added to redisperse.

  2. What is the composition/information on ingredients of the aqueous suspension?

    1 answer
    1. As mentioned on the Datasheet associated with this product, the latex bead suspensions are composed mainly of polymer particles and water, with small amounts of surfactant, sodium bicarbonate, and potassium sulfate. A typical latex bead contains the following:
      • Water >69.0%
      • Polymer 30.0%
      • Surfactant 0.1–0.5%
      • Inorganic salts 0.2%
