- Recommended Usage
This streptavidin product 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 DyLight™ 649 conjugation. It is recommended that the reagent be titrated for optimal performance for each application.
- Application Notes
Streptavidin-DyLight™ 649 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-DyLight™ 649 is 60 kD and Streptavidin alone is 52 kD.
