      2. Troubleshooted and Re-tred PCR for user ends for reporter plasmid
      3. Called IDT about pcr assembly – they said Gibson tends to work better, no mutations, all in one tub. If we must PCR assembly – add DMSO, hotstart reaction, anneal at 68-70C (we did this).
      4. Get methylated biobrick sequenced
      5. Only sequence ptet GFP 11, if verified make sure to note on LIMS that we are only using ptet GFP 11
