90nm Methylated (methoxy-PEG5000-SH) Gold NanoUrchins Size:0.5ML 20nm standard gold nanoparticles (100mlComposition: Methylated (methoxy PEG thiol, 5kDa) Gold NanoUrchins Core Size: 90nm Adsorption max: 630nm Optical Density (OD): 50 Particles per ml: 2. 69E+11 Formulation: Supplied in USP grade purified water Properties These non protein binding methylated gold nanourchins have a narrow size distribution (CV of less than 10%), prolonged shelf life and reduced aggregation propensity due to the protective PEG layer. Low batch to batch variability (+ 2nm)
