The mixed bottle is toast. The unmixed MIGHT be good, but I wouldn't put money on it. Why are you storing them outside the fridge? Powder vials should be stored in the fridge or freezer for long term storage. Freezer (-20 centigrade) is the standard. When reconstituted it depends on the concentration and solvent. Reconstituted only in water they lose activity. Reconstituted in sodium phosphate buffer with 0.9% benzyl alcohol they are fairly stable for short term. Dilute recons are not stable--do not freeze dilute recons. Larger concentrations above ~ 100 mcg/mL are relatively stable in water at refrigerated temperature for about 60 days.
Degradation in solvent is concentration dependent and solvent dependent. Obviously do not expose to light unless using them.
