Streptavidin silica particles, red fluorescent

Red Fluorescent Streptavidin Silica Particles:

Nanocs offers a number of Red fluorescent and streptavidin coated silica nanoparticles and microbeads with particle size ranging from 50 nm to 12 microns. Our proprietary synthetic methods ensure the strong fluorescent signal, high photostability of these fluorescent beads. Our red fluorescent particles have excitation/emission wavelength around 547 nm/576 nm. On the other hand, streptavidin coating on these fluorescent beads can be used to bind to biotinylated ligands, such as biotinylated peptides, oligonucleotides or enzymes with high affinity. These particles have wide applications in flow cytometry, lateral flow assay, gene sequencing and many other bioassay development. These streptavidin particles can include various fluorescent dyes from UV region to near IR, include coumarin, fluoresceins, rhodamines, cyanine dyes, alexa fluor dyes. Customer conjugation and modification is available upon request.
