TAQ should be stable, it can be shipped at ambient temperature by P-E. It 
is sterile until it's opened.  Once opened, freezing is recommended in order 
to keep anything from growing in it. If in doubt, I suggest only keeping the 
tubes that have not yet been opened and running a control reaction when 
they are first used.
