- Recommended Usage
Each lot of this Streptavidin-Brilliant Violet 650™ 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 Brilliant Violet 650™ conjugation. For immunofluorescent staining, we recommend using ≤0.125 µg in 100 µl staining volume per million cells. It is recommended that the reagent be titrated for optimal performance for each application.
Brilliant Violet 650™ excites at 405 nm and emits at 645 nm. The bandpass filter 660/20 nm is recommended for detection, although filter optimization may be required depending on other fluorophores used. Be sure to verify that your cytometer configuration and software setup are appropriate for detecting this channel. Refer to your instrument manual or manufacturer for support.
