Application

Latex beads, amine-modified polystyrene, fluorescent yellow-green have been used:
  • in the characterization of nano- and microplastics
  • in tendon preparation to label tendon fascicles to enable precise localization of the tissue surface
  • in phagocytosis assay to label spleen cells

Biochem/physiol Actions

Polystyrene latex beads can be used to create latex agglutination systems. It can be used to study the transmission of Mycobacterium leprae, the causative pathogen of leprosy. These beads are also utilized to develop a method for mass screening for both pulmonary and extrapulmonary tuberculosis.

Questions

1–3 of 3 Questions  
  1. Hi I wonder if this particle is sterile, I need it sterile because I will use it during cell incubation, is the suspension with NaN3 or without? Regards Ravi

    1 answer
    1. This product is not sterile. The Safety Data Sheet indicates the presence of sodium azide in the product formulation.

  2. What is the linear chemical formula and molecular weight of the various latex beads with product codes L1528, L1403, L9902, L9529, L9904, L9654, L0780, L0280, L3030, L3280, L5530, L2778, L4655, L4530, L5155, and L1030?

    1 answer
    1. The supplier does not provide the molecular weight or a molecular weight range for any of the latex beads. Polystyrene has a linear formula of [CH2CH(C6H5)]n. There are no exact values for the molecular weight available, although some internet sources may state a range of 100,000 to 400,000 amu. The polystyrene can be unmodified or surface modified. The dye is encapsulated inside the surface functionalized (amine or carboxylic) PS beads, which are well dispersed in the cationic surfactant assisted solution. The dye is not strongly bonded, and the PS may have a porous structure, so the dye can come out when changing to an organic solvent.

  3. Hi, can you please provide me some information about the density of amines loaded on the surface of this particles?

    1 answer
    1. The amine content is not specifically quantified on a lot-to-lot basis. Historical data indicate a total parking area of 30 to 300 angstroms squared per charge group. Unfortunately, no further information is available.
