Last Friday I was distracted as I was getting ready to head home and I forgot to put the ECL kit back in the fridge (needs to be stored at 4C). It was sitting out at room temp (~21C) for a total of about 36 hours before I realized my mistake. I'd imagine luminol is fairly stable, but I worry that the H2O2 has degraded to water a little bit. Both reagents were protected from light.
Has anyone ever made this mistake? Do you think that the kit is ruined?
