SpecNano™ Biotin Conjugated Gold Nanostars, 50 nm(CGSB-50)


50 OD biotin gold nanostars, 50 nm diameter, absorbance max 585 nm, are monodispersed gold nanostars conjugated with biotin molecules and have a narrow size distribution (<10%). There is a PEG (10 kDa) spacer-SH between the gold surface and biotin molecules. These nanostars are suitable for binding of streptavidin labeled conjugates.
