Biochem/physiol Actions
Polystyrene latex beads can be used to create latex agglutination systems. Polystyrene latex beads have been used to study the transmission of Mycobacterium leprae, the causative pathogen of leprosy, as well as to develop a method for mass screening for both pulmonary and extrapulmonary tuberculosis.

Is the fluorescent tag embedded in the nanoparticle or attached to its surface? I would like to know if the fluorescent tag can interact or bind to other molecules or ions present in the media.
1 answer-
The dye is encapsulated inside the PS beads. Since these products are not tested in-house, we cannot confirm whether the fluorescent tag may interact with or bind to other molecules or ions present in the media.

I understand from a previous question that a cationic surfactant was added, could you specify what it is?
1 answer-
The specific nature of the surfactant is proprietary information.

What will be the concentration of plastics in 1ml? Can I add distilled water to make stock solution?
1 answer-
The amine-modified polystyrene latex beads are suspended in distilled water with a minimum amount of proprietary cationic surfactant (0.2%). The concentration of solids (plastics) is >/= 2.5%.
