Creative Diagnostics offers a wide size range of coloured particles in polystyrene matrix and silica matrix. Our coloured particles covalently bind or encapsulate dyes in red, blue, black and other colors which are prepared using internally-dyed technologies to prevent leakage and keep stable in aqueous media. They are modified with functional groups for conjugation of proteins, antibodies, oligonucleotides and other molecules. Polystyrene particles are also coupled with proteins like streptavidin, protein A/G and several kinds of secondary antibodies for specific conjugation. The coloured particles are suitable for visual or microscopic identification and qualitative and quantitative detection such as applications of imaging and diagnostic studies, immunoassays including flow investigations, membrane checks.
