Silica Particles, Biotin Labeled

Description:

Biotinylated silica nanoparticles or microbeads from Nanocs have narrow size distribution yet with multiple size selection from 20 nm to 50 microns. Standard deviation of these particles is in the range of 10% of listed size parameter. Our biotin beads were synthesized by covalently attaching biotin ligands on the surface of these silica beads and therefore, they are very stable in various solution. In addition, our biotinylated silica beads have high biotin loading capacity and therefore, strong binding capability torward avidin or streptavidin. These biotinylated particles have wide applications in diagnostic reagents and bioassay development. They can be further modified with different surface coatings and functional groups. We also provide fluorescent biotin silica beads for bioassay development. Nanocs surface modified silica particles provide more choices for in-vitro or in-vivo applications of those nanoparticles. Customer conjugation and modification is available upon request.
