Gold Nanoparticle Size Optimization Panel (medium range, endotoxin free)

Sizes: 20nm, 40nm, 60nm and 80nm gold nanoparticles

Surface Composition: Citrate

Quantity: 20ml of each size at OD=1

Purity: >99% reactant free

Endotoxin Levels: <0.5 EU/mL

Buffer: Supplied in 0.1mM phosphate buffered saline


Four sizes of unconjugated gold nanoparticles spanning the medium size range from 20nm to 80nm combined in a convenient kit for testing of optimal size and suitability during your protocol development. Ideal for conjugation of antibodies for use in lateral flow and blotting applications.


These gold nanoparticles have a  narrow size distribution (CV of less than 12%), high protein binding capability and are more than 95% spherical. Low batch to batch variability (+/- 2nm) assures you as a customer always end up with a product within the specified size range ordered. All batches have been validated for endotoxin levels using the Limulus amebocyte lysate (LAL) test.


Store product away from direct sunlight at 4-25°C. Lower temperature prolongs the shelf life of the product.

Do Not Freeze

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