Streptavidin binds to biotin with high affinity. Streptavidin-Alexa Fluor® 594 is useful for detecting biotinylated antibodies.Product Details
- Human, Mouse, Rat, All Species
- Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide.
- Streptavidin was conjugated with Alexa Fluor® 594 under optimal conditions. The solution is free of unconjugated Alexa Fluor® 594.
- 0.5 mg/ml (concentration relates to the Streptavidin only component of the conjugate)
- Storage & Handling
- The streptavidin-Alexa Fluor® 594 solution should be stored undiluted between 2°C and 8°C, and protected from prolonged exposure to light. Do not freeze.
IF - Quality tested
IHC-F - Validated
- Recommended Usage
This streptavidin product is quality control tested by immunofluorescence in microscopy. The concentration provided is based upon molecular mass of streptavidin independent of any additional molecular mass that might be added by the Alexa Fluor® 594 conjugation. For flow cytometric staining, the suggested use of this reagent is ≤0.125 µg per million cells in 100 µl volume. For immunohistochemistry, a concentration range of 2.5-5 µg/ml is suggested. It is recommended that the reagent be titrated for optimal performance for each application.
* Alexa Fluor® 594 has an excitation maximum of 590 nm, and a maximum emission of 617 nm.
Alexa Fluor® is a trademark of Life Technologies Corporation.
