Uniform latex particles are used in a wide range of applications that exploit their physico-chemical properties in sophisticated immunoassay formats, both in medicine and veterinary science research.

Manufacture latexes with essentially uncharged surfaces for immobilisation of biomolecules by adsorption, and surfaces having carboxyl groups, allowing covalent immobilisation of ligands.

Latex particles have been employed for many years in a variety of assay formats for rapid, user-friendly and cost-effective tests, including slide agglutination, membrane migration, particle capture, turbidimetry, nephelometry, and “particle enhanced” assays.

The intensely coloured HiDye™ particles offer all the features of the white particles with the added advantage of intense colour. As the dye is not surface bound, it does not interfere with the binding of the ligand. HiDye™ particles are ideal for membrane migration assays and cell labelling studies.
