Things to Do
1. Request Japanese plasmid which overexpresses leucine in E. coli- DONE
2. Ask Professor Prather if she thinks that leucine is limiting in our reaction- DONE
3. Perform experiment that Reshma suggested (add .02 g/L of leucine to J45600 and J45900 cultures)
4. Resend request to Yale for aroF- aroG- aroH-, make sure it gets ordered today- DONE (AB3257 (aroF- aroG- aroH-) is on its way in today's mail!!!)
5. Ask Endy if they think that it is a good idea to add new promoters/RBSs to precursor devices in parallel with obtaining overexpressing strains/what overall goals should be a priority- DONE
6. Run GC samples from yesterday's time course- WORKING ON IT
7. Meet with Alex about GC (2 PM)- DONE (need to prepare isoamyl acetate in heptane and heptane extraction of LB media, Alex seemed optimistic)
8. Print out GC procedure for isoamyl acetate for meeting- DONE
