Silica beads, FITC lableled

Silica Nanoparticles, fluorescein (FITC) Labeled:

Nanocs offers a number of Fluorescent silica nanoparticles and silica microbeads with fluorescent signal from UV region to near infrared area. Fluorescein labeled silica beads are green fluorescent particles with excitation/emission wavelength around 490 nm/515 nm. Silica particles from Nanocs have narrow size distribution yet with multiple size selection from 7 nm to 50 microns. These particles are suspended in 1% aqeuous solution. Standard deviation of these particles is in the range of 10~20% of listed size parameter. These particles have wide applications in diagnostic reagents and bioassay development. They can be further modified with different surface coatings and functional groups. Nanocs fluorescent labeled silica particles provide more choices for in-vitro or in-vivo applications of those nanoparticles. These particles 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.
