PerCP-streptavidin conjugate
Streptavidin conjugates are widely used together with a conjugate of biotin for specific detection of a variety of proteins, protein motifs, nucleic acids and other molecules since streptavidin has a very high binding affinity for biotin. This PerCP-streptavidin conjugate comprises streptavidin (as the biotin-binding protein) with PerCP covalently attached (as the fluorescent label). It is commonly used as a second step reagent for indirect immunofluorescent staining, when used in conjunction with biotinylated primary antibodies. It is a very valuable tool for biotin-streptavidin-based biological assays and tests using flow cytometry platform. A variety of the complementary biotinylated reagents are available from numerous commercial vendors.
Top) Spectral pattern was generated using a 4-laser spectral cytometer. Spatially offset lasers (355 nm, 405 nm, 488 nm, and 640 nm) were used to create four distinct emission profiles, then, when combined, yielded the overall spectral signature. Bottom) Flow cytometry analysis of whole blood cells stained first with CD4–biotin followed by PerCP–streptavidin conjugate. The fluorescence signal was monitored using an Aurora spectral flow cytometer in the PerCP–specific B8-A channel.
