- use 2ul to run a TBE gel to check the PCR results, then save 18ul for backup, and use the rest to do Qiaquick column purification elute in 30ul EB.
- Use Nanodrop to check the concentration of the purified PCR product.
- TBE gel result:
- Prepare the samples for sequencing:
- USE Pre-Mixed Samples Preparation Guidelines from Genewiz to mix the DNA and custom primers.
- The DNA size is 200-500bp, so we use 10ng of DNA in 10ul volume (~1ng/ul)
- Add 1ul of purified PCR product with 9ul of ddH2O.
- Add the Forward primer for sequencing, dilute the Forward primer to 5uM, add 5ul of primer(total of 25pmol) and get a final volume of 15
