Batch Summary
Use this page to keep track of competent cell production. See the competent cell protocol for more information.

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.
Notes: While ODing culture, cells were not ekpt on ice/stored in fridge. Poured into centrifuge tubes on ice, but tubes were not pre-chilled.
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.
Notes: While ODing culture, cells were not ekpt on ice/stored in fridge. Poured into centrifuge tubes on ice, but tubes were not pre-chilled.
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.
Notes: While ODing culture, cells were not ekpt on ice/stored in fridge. Poured into centrifuge tubes on ice, but tubes were not pre-chilled.
