1.  Incubation at 50°C results in 3 fold higher activity.

2.  For enzymes that cannot be heat-inactivated, we recommend using a column for cleanup (such as the Monarch® PCR & DNA Cleanup Kit), or running the reaction on an agarose gel and then extracting the DNA (we recommend Monarch Gel Extraction Kit), or performing a phenol/chloroform extraction.
