Colloidal Gold Conjugates:

We offer the following colloidal gold conjugates for use in lateral flow immunoassays, western blotting and other immunoassays requiring a non-enzymatic colorimetric readout. Our conjugates, developed in collaboration with a local immunodiagnostics company, range in size from 20-30 nm. The product volumes and concentrations are primarily for lab-scale testing purposes. For diagnostics companies looking for larger quantities of gold conjugates, we can supply liter quantities of conjugates at higher concentrations (10 O.D.) and complete batch documentation.
