商品詳情參考文獻(xiàn) 相關(guān)資料

Product Details

Composition: Citric acid stabilized gold colloid
Core Size: 250nm
Particles per ml: 7.1E+8
Volume: 20ml
Formulation: Supplied in 0.1mg/ml citrate supplemented with a proprietary stabilizing solution.

Intended 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, please see our standard gold nanoparticles.

Properties

Cytodiagnostics 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, see Tech Note #104.

Our gold nanoparticle preparations have a narrow size distribution (CV of less than 8%), increased stability 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.

When stored as specified the product is stable for at least six months.
