Can diluted/reconstituted ChromaLink™ biotin be frozen for storage longer than one day, then reused at a later time?

The diluted biotin reagent should NOT be used after 1 day, even if frozen. Should be used fresh, as hydrolysis can occur. The sulfo-ChromaLink™ Biotin reagent is stable for an hour or for the day (at most) if kept at 4oC…but not longer than that. Hydrolysis occurs.
