Batch Notes
001
This is the first batch attempting to fully standardize competent cell production. Also Kitwa's first batch! And a resounding success!
The efficiency test/test transformation used a single 250ul aliquot (randomly chosen). Three transformations were done using our standard template and protocol. Important: In following productions we will test the first and last of the aliquots.
002
OD600nm value at 15.5 hours was 0.26, and cells were re-placed in the shaker for another 0.5 hours. OD value afterward was 0.40.
003
OD600nm value at 15.5 hours was 0.16, and cells were re-placed in the shaker for another 0.5 hours. OD value afterward was 0.23.
