SpecNano™ Protein A Conjugated Gold Nanostars, 50 nm, 3 OD(CGSA-ProA-50-3)


3 OD protein A conjugated gold nanostars, 50 nm diameter, absorbance max 585 nm, are monodispersed gold nanostars conjugated with protein A and have a narrow size distribution (<12%). These nanostars can be used as antibody probes in assays such as lateral flow, immunoblotting, ELISA, light microscopy and electron microscopy applications, also be used for capturing of antibody species with affinity for protein A to the gold nanostars surface. Working dilution: 1:10-1:100.
