Far-red fluorescent Alexa Fluor 635 streptavidin has absorption/emission maxima of ∼633/647 nm. Streptavidin is a nonglycosylated biotin-binding protein that is isolated from bacteria and has a near-neutral isoelectric point. It is widely used to detect biotinylated probes, because it reportedly exhibits less nonspecific binding than does the glycosylated, biotin-binding protein, avidin.

常见问题解答 (FAQ)

I am planning to use a fluorescent streptavidin labeled conjugate. What are the storage conditions and shelf life for the lyophilized powder and reconstituted solution?

In the lyophilized powder form, the fluorescent streptavidin labeled conjugate is stable for six months when stored at -20 degrees C, desiccated, and protected from light. The reconstituted solution is stable for approximately six months when stored at 4 degrees C, protected from light, with the addition of sodium azide to a final concentration of 5 mM or thimerosal to 0.2 mM. For longer storage, we recommend dividing the solution into aliquots and freezing at -20 degrees C, protected from light. Avoid repeated freezing and thawing of the solution.

I am planning to use a fluorescent streptavidin labeled conjugate. How should I prepare the working solution of the conjugate?

The fluorescent streptavidin labeled conjugate solution can be made by dissolving the powder in 0.5-1.0 mL of PBS or other suitable buffer. For details, please refer to page 4 of the "Streptavidin and Fluorescent Conjugates of Streptavidin" manual (https://assets.fishersci.com/TFS-Assets/LSG/manuals/mp00888.pdf).
