Recommended Usage

Each lot of this Streptavidin-PE/Cyanine5 is quality control tested by immunofluorescent staining with flow cytometric analysis. The concentration provided is based upon molecular molar mass of streptavidin independent of any additional molecular mass that might be added by the PE/Cyanine5 conjugation. For immunofluorescent staining, the recommended use of this reagent is = 0.125 µg per 106 cells in 100 µl staining volume. It is recommended that the reagent be titrated for optimal performance for each application.

Excitation Laser
Blue Laser (488 nm)
Green Laser (532 nm)/Yellow-Green Laser (561 nm)
Application Notes

Streptavidin-Phycoerythrin/Cyanine5 (PE/Cyanine5) is useful as a second step reagent for indirect immunofluorescent staining, when used in conjunction with biotinylated primary antibodies. The average molecular weight of Streptavidin-PE/Cyanine5 is 480 kD and Streptavidin alone is 52 kD.

Additional Product Notes

BioLegend is in the process of converting the name PE/Cy5 to PE/Cyanine5. The dye molecule remains the same, so you should expect the same quality and performance from our PE/Cyanine5 products. Please contact Technical Service if you have any questions.
