Is Taq polymerase still active after staying at 10C for one day?

I accidentally left the polymerase tube outside the fridge for one day, (temp is around 10C since it previously in the ice bath...). Can I still use this Taq polymerase? Thanks!

    Unlimited ligation works!

Yes. Give it a try. It should be okay from this miss adventure.
May your PCR products be long, your protocols short and your boss on holiday

Yes, almost certainly. Taq is a high temperature enzyme which survives 95C in a thermocycler. The main danger would be bacterial or fungal growth, but this is unlikely over a day, and probably would be inhibited by other components of the enzyme buffer.
