Recommended Usage

It is recommended that the reagent be titrated for optimal performance for each application. The concentration provided is based upon molecular mass of streptavidin independent of any additional molecular mass that might be added by the Cyanine3 conjugation.

Application Notes

The average molecular weight of Streptavidin-Cy3 is 60 kD and Streptavidin alone is 52 kD.

Additional Product Notes
BioLegend is in the process of converting the name Cy3 to Cyanine3. The dye molecule remains the same, so you should expect the same quality and performance from our Cyanine3 products. Please contact Technical Service if you have any questions.
