Fluorescent Streptavidin Microspheres

Polysciences offers fluorescent streptavidin-coated microspheres across multiple sizes (1 µm, 2 µm, 6 µm), including Fluoresbrite® YG variants and plain formats. These particles provide strong, nearly irreversible streptavidin–biotin binding for applications like affinity isolation, assay development, and imaging.
