Notes
1. The reaction temperature can be optimized between 62℃ and 68℃ according to the primer condition.
2. The packaged reagents should not be exposed to air for a long time.
3. The experiment shall be conducted in a standardized manner, including the preparation of reaction system, sample treatment and sample addition.
4. It is suggested to prepare reaction system in the ultra-clean table and add templates in the fume hood of other rooms to avoid false.
