70nm Methylated (methoxy-PEG2000-SH) Gold NanoUrchins Size:1ML 17E-12 * All concentrations asComposition: Methylated (methoxy PEG thiol, 2kDa) Gold NanoUrchins Core Size: 70nm Adsorption max: 600nm Optical Density (OD): 50 Particles per ml: 6. 0E+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)
