Streptavidin Background

The Streptavidin Protein Terbium chelate is a universal tool for TR-FRET assays that can bind biotinylated molecules. This product uses high-purity streptavidin (SA) covalently conjugated with Tb³⁺ chelate, and it can be used in combination with other Acceptors directly or indirectly labeled with fluorescent dyes. When the Donor and Acceptor come into close proximity (within a distance of less than 10 nm), a FRET reaction occurs: the 620 nm signal emitted by the Donor upon excitation by a specific light source is received by the Acceptor, which then emits a 665 nm signal.

    Using streptavidin coated for ELISAs made it easier for my team to run assays in a timely matter. It was easy to use since the coating part was taken care of by Acro and will continue to order them
