50nm Endotoxin Free Gold Nanoparticles

Composition: Citrate stabilized gold colloidCore Size: 50nmAbsorption max: 536nmParticles per ml: 3.51E+10 Purity: >99% reactant free Endotoxin levels: <0.5 EU/mLFormulation: Supplied in 0.1mM phosphate buffered saline (PBS) Intended use: Our extensively purified endotoxin free gold nanoparticles are ideal for sensitive applications requiring a minimal amount of contaminants, such as cellular toxicity studies, immunological studies, and aseptic assays. This product is well suited for conjugate development by passive adsorption of proteins and other ligands to the gold nanoparticle surface. The resulting conjugate can then be used in downstream applications. Properties Cytodiagnostics endotoxin free gold nanoparticles are made using a unique proprietary protocol resulting in pure, endotoxin free particles with superior size distribution and shape compared to that of the leading competitor.  Our gold nanoparticle preparations have a narrow size distribution (CV of less than 15%),
