Streptavidin has an extremely high binding affinity for biotin, which can be exploited to offer a powerful secondary method of detection when the streptavidin is conjugated to a fluorescent protein, enzyme or gold nanoparticle.
All of the detection labels within our range of conjugates are covalently linked to streptavidin, forming highly stable conjugates with a long shelf life.
