Unpassaged live mouse primary retinal pigment epithelial cells engulfed biotinylated photocreceptor outer segments (POS) coupled to Cyanine5 Streptavidin (red). Cells were subsequently stained with Flash Phalloidin™ Green 488 (green) and DAPI (blue).

Product Details

Verified Reactivity
Human, Mouse, Rat, All Species
Formulation
Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide.
Preparation
Streptavidin is conjugated with Cyanine5 under optimal conditions.
Concentration
0.5 mg/ml (concentration relates to the Streptavidin only component of the conjugate)

Application

FC - Quality tested

ICFC - Verified
Recommended Usage

Each lot of this Streptavidin-Cyanine5 is quality control tested by immunofluorescent staining with flow cytometric analysis. The concentration provided is based upon molecular mass of streptavidin independent of any additional molecular mass that might be added by the Cyanine5 conjugation. For immunofluorescent staining, the recommended use of this reagent is = 0.5 µg per 106 cells in 100 µl staining volume. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

Streptavidin-Cy5 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-Cy5 is 60 kD and Streptavidin alone is 52 kD.

Additional Product Notes

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