It was left out for overnight in room temperature. Can we use it for experiments or is it expired? SDS says it should be stored in -20. Has anyone had the same issue and tried to use it?
The 6-Bnz-cAMP is a membrane permeable and selective cAMP-dependent protein kinase (PKA) activator. It is a sodium salt and keeping at room, temperature overnight may not be good enough to degrade it. After noticing the issue you might have again kept it at -20 degree C. It would have been the matter of concern once it is reconstituted, hope the vial containing powder form was kept overnight at RT but not the diluted reconstituted or the diluted vial.
The company provides SDS wherein recommended information is given for the product long storage, stability with minimum or no degradation rate. Of course, you must be careful with your chemical storage as per the recommendation of the company SDS manual, to me however, it is not a great mistake that could affect the stability of the sodium salt to the extent which makes you reluctant not to use it as PKA Activator for your experiment.
