Matters needing attention
1. when using, please mix it upside down gently to avoid foaming, and use it after slight centrifugation. For the preparation and sub packaging of reaction solution, please use new (non RNase contaminated) gun heads, microtubes, etc. to ensure that all reagents are free of RNase contamination.
2. in order to ensure effective reaction, high-quality DNA template shall be used.
