Place 5ml of Lauria Bertaini broth in a plastic container.
Place the taq polymerase extract in the broth-filled container and heat for 12 hours at 37 degrees Celsius.
Add 0.2-0.5mM of IPIG and continue heating at 37 degrees Celsius for another 12 hours.
Mix 50mM Tris-HC1, pH 7.9, 50 mM dextrose and 1mM EDTA together in a plastic container to create a buffer.
Wash the taq polymerase with detergent, place in the buffer and insert 4 mg/mL of lysozyme.
Place the container in a room temperature atmosphere for five minutes.
Place the substance in a 75 degrees Celsius atmosphere for 30 minutes.
Remove the purified taq polymerase extract and store as desired.
