TO CHECK/CONFIRM
- 'K1' (mentioned on 9/250 -> where did it come from?
- 9/25 - miniprepped parts (inoculated 9/24) were plasmids from karita sensei? biobrick parts pcr-cloned on 9/23? why where these parts transformed immediately after miniprep?
- 'CelB, Cel44A' etc vs 'Cel5, Cel8, Cel44' which nomenclature refers to what (received plasmids, pcr product?)
