Founded in 1986, BBI is the world leader in the manufacture of high quality gold and silver reagents for research and diagnostic applications. Our policy has always been to provide outstanding products, manufactured and tested with the highest emphasis placed on reliability, sensitivity and reproducibility. In addition, our vast experience enables us to provide our customers with a comprehensive technical support programme.

Our life science product range is made up of gold and silver colloid and gold conjugates, as well as our Nexus range comprising gold Nanorods and gold Nanobeads. We also provide a complete custom conjugation service, developing gold conjugates outside of our catalogued range. We welcome discussion with our customers to consider the possibilities of creating any type of gold conjugate to meet your requirements.

BBI’s unique recipe gold colloid has been market leading for over 25 years due to its superior quality, consistency and performance, offering excellent stability and sensitivity characteristics. There are several advantages of choosing BBI’s gold colloid:

 • Lowest available coefficient of variation (CV)

• The choice of particle size makes it possible to study antigens microscopically

 • Allow multiple labelling of antigens on tissue sections

 • Labelling is completely unequivocal

 • Provides a permanent label

 • Quantitation under the electron microscope is possible due to its particulate nature

 • The optical properties mean there is a variation in colour from red to pink to orange depending on particle size, a property that can be successfully exploited in a range of applications

 • Known to be catalytically active for a range of commercially important reactions

A colloidal gold conjugate consists of a suspension of gold particles coated with a selected protein or macromolecule (such as an antibody). BBI has a range of EM grade products that combine different antibodies on the range of particles predominantly 2, 5, 10, 15, 20, 30 & 40nm. BBI’s gold conjugates provide the following benefits.

 • Binding to BBI’s superior quality gold colloid ensures a very low level of clustering while maintaining high level stability and sensitivity

 • Only highest quality antibodies and proteins are used, meaning consistently reliable products

• BBI’s gold conjugates have more than 85% singlets
