Gold colloids for diagnostic applications

Metalor manufactures colloidal gold from high purity gold salts, which exhibit superior labelling properties in rapid test diagnostic applications.

These are the properties which distinguish our gold colloids:

• High purity
• High sensitivity
• High stability

Each batch is systematically controlled: absorbance, size, particle size distribution (PSD) and uniform spherical shape are analysed. Four sizes are currently available: 10 nm, 20 nm, 30 nm, 40 nm.

Customized protein conjugation is available upon request. Combined with our gold colloids, the custom conjugation services allow the development of high quality conjugates, using reagents supplied by the customer or sourced by Metalor.
