Final answer:
Shake thermo gel vigorously for 30 minutes before use to remove impurities and ensure proper gel formation.
Step-by-step explanation:
Before using thermo gel, it is recommended to shake vigorously for 30 minutes in order to get rid of any acrylamide that did not form a polymer and any free radicals produced during polymerization.
Typically, thermo gel is used in the process of electrophoresis, where it is polymerized to form a gel matrix. This gel matrix is then used to separate and analyze biomolecules such as DNA or proteins. The shaking step helps to ensure that the gel forms properly and that any impurities are removed.
