Description

General description

Micro Particles or Latex Beads, commonly known as polystyrene microparticles, are negatively charged colloidal particles. The microparticles are produced through a polymerization reaction of styrene under controlled conditions. The conducive environment of the reaction induces spontaneous coalescent bead formation. The biotin-streptavidin system is the strongest noncovalent biological interaction known, having a dissociation constant, K(d), in the order of 4x10(-14) M. The beads are magnetic in nature and coated with streptavidin for enhanced binding. Micro Particles or Latex beads are supplied in aqueous solutions composed of polymer particles with water. Polystyrene′s refractive index at 589 nm is 1.5905 and 1.602 at 486 nm.

Superparamagnetic polystyrene particles

Application

Easily conjugated with biotin, making them useful for several detection assays,.

Micro Particles or Latex Beads is used for a wide variety of applications like:

• Electron Microscopy.
• Cell Counter Calibration.
• Immunodiagnostics, especially for latex agglutination tests, and
• Phagocytosis Research.

Microparticles with streptavidin are easily conjugated with biotin for use in various detection assays
