Is it just the master mix without the primers and templates added yet? In that case there is a good chance it will work fine. If possible run a couple of samples to validate the performance.
A test is the only way to know for certain. However, it will almost certainly be OK - remember the master mix is exposed to high temperatures during an amplification, so it will be stable at room temperature for a long time.
First Of all you must know the condition of storing your product.
second thing you can tell us what is the weather condition in this 24 hrs (i just try to know the conditions of weather in your lab).
most of PCR master mix can tolerate 4 C for some of time.
if you dont know the condition of weather as temperature and humidity in your lab at this 24 hrs which your PCR master mix was outside the storing unite the only way to examine the vitality of this chemicals by running PCR reaction with positive sample using primer that you confirm it activity.
