Size: 20ml
Optical Density: 1 OD

Composition: Citrate stabilized gold colloid
Core Size: 100nm
Absorption max: 572nm
Particles per ml: 3.84E+9
Formulation: 
Supplied in 0.1mM phosphate buffered saline (PBS)

Intended use: 
Conjugate development by passive adsorption of proteins and other ligands to the gold nanoparticle surface. The resulting conjugate can be used in blotting, electron microscopy and immunohistochemistry applications. 

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

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.
