Gold Nanoparticles (C09-0901-409)

Composition: Citrate stabilized gold colloidCore Size: 20nmAbsorption max: 524nmParticles per ml: 6.54E+11Intended use:Adsorption of thiolated ligands such as oligonucleotides and polyethylene glycols. Also, due to the increased stability, these gold nanoparticles are ideal for use in physical and optical applications.Note: This product is not ideal for protein adsorption. For gold nanoparticles suitable for adsorption of proteins and other ligands for conjugate development.Properties :unconjugated gold nanoparticles are made using a unique proprietary protocol resulting in 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%), exceptional protein adsorption properties and more than 95% spherical particles. In addition, low batch to batch variability (+/- 2nm) assures you as a customer always end up with a product within the specified size range ordered. All of our batches go through stringent quality control prior to shipment to our customers using dynamic light scattering to guarantee size and monodispersity and lot specifications are supplied with each product.Storage:Store product away from direct sunlight at 4-25°C. Lower temperature prolongs the shelf life of the product. Do NOT freeze. Freezing causes irreversible aggregation of the gold nanoparticles. When stored as specified the product is stable for at least six months.Product Data. Specifications and Purity: 20nm, 1 OD, supplied in 0.1mg/ml stabilized suspension citrate buffer, 524nm abs. max.
