- Conclusion:
- The two negative controls were clean. Therefore the ~120bp bands are likely due to self-ligation of the adaptors.
- I think I can simply repeat the amplification on the ligation products, and then do PAGE size selection to obtain the libraries of the desired sizes. Need to double check with Alice.
