Streptavidin, Alexa Fluor® 647 conjugate

Category: Products & Services > Antibodies & Secondary Detection Reagents > Avidin, Streptavidin & Biotin > Streptavidin

Alexa Fluor® 647 streptavidin comprises a biotin-binding protein (streptavidin) covalently attached to a fluorescent label (Alexa Fluor® dye). Streptavidin has a very high binding affinity for biotin, and a conjugate of streptavidin is commonly used together with a conjugate of biotin for specific detection of a variety of proteins, protein motifs, nucleic acids, and other molecules (for example, a biotinylated primary antibody bound to a protein target can be detected with a fluorescently labeled streptavidin). Strategies similar to this are used in many detection protocols including western ...
