Colored Latex Microspheres, 200-400 nm (CAT#: STEM-BC-3089-ZJF)

These colored latex microspheres are designed as visible labels for diagnostic and analytical assays. Red, blue, and black particle series are available. Listed particle sizes include 200, 300, and 400 nm. Carboxyl-functionalized particles provide reactive surfaces for covalent biomolecule coupling. Streptavidin-functionalized variants support capture of biotinylated reagents. The visible particle colors enable signal generation without fluorescence instrumentation. A 5% solids concentration is provided for the listed formulations. Package sizes support laboratory development, pilot testing, and larger-volume use. The primary applications are lateral-flow chromatography and latex-agglutination assays.
