Trizol stability - (Sep/17/2010 )

Yesterday i opened the new 500 ml bottle of trizol reagent. I used it and forget to store the rest of it in refrigerator. i left it at room temperature (around 30 C), overnight.
Can anyone tell me..........will it be still working.

yeah still can use. hope you didn't leave the cap open. I've been keeping my Trizol at 4C for over 2 years now. still works fine.
