Each lot of this Streptavidin-FITC 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 FITC conjugation. For immunofluorescent staining, the recommended use of this reagent is ≤ 0.25 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)
- Application Notes
-
Streptavidin-FITC is useful as a second step reagent for indirect immunofluorescent staining, in conjunction with biotinylated primary antibodies. The average molecular weight of Streptavidin-FITC is 60 kD and Streptavidin alone is 52 kD.
