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? Product FAQ

Answer

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.
