Gold Particles are of highest quality and can be used in production of diagnostic tests as well as conjugation studies of proteins and antibodies. The particles have a very narrow size distribution ( CV between 5% and 15% depending on size ) and are available from 2 nm to 250 nm. The number of particles/ml is given in the product/ordering table. The solutions are stabilized with citrate Gold colloids or sols are available in a number of different sizes. There are 14 different gold colloid sizes and offered in four packing sizes. The products are best stored at room temperature, although storage at 4°C is an option. However, temperatures too close to freezing will destabilize the sol, causing aggregation and product loss. All gold colloids are supplied at an OD of 1 at 530 nm except for the 2 nm particle size which is approximately OD 0.2 at 460 nm. Prices for larger quantities on request.
