Streptavidin / Alexa Fluor 568 / N/A

Product Details

Description	Alexa Fluor® 568 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 blots, flow cytometry, imaging and microscopy, and microplate assays. Alexa Fluor® dye streptavidin conjugates are supplied as 1 mg lyophilized product or in 0.5 mL volumes of a 2 mg/mL solution.

About Alexa Fluor 568
Alexa Fluor™ 568 (AF568, Alexa 568) has an excitation peak at 578 nm and an emission peak at 603 nm, and is spectrally similar to Rhodamine B. Alexa 568 is commonly used fluorescence and super-resolution microscopy. Many flow cytometers are equipped with 561nm lasers, so while Alexa 568 can be used for flow cytometry, PE or NovaFluor Yellow 570 are more commonly used due to their brightness and spectral characteristics.
