Things we did today
Grace & Norman
- Thaw test for PCC6803 and DH5-α
- Made LB and LB + amp media
- Made 1000X amp stock solution, stored in 4C freezer
- Tested competency of DH5-α (see experiment)
- Counted colonies to determine number of cells grown to OD600 = 0.3
- Cells were cryoperserved, OD600 = 0.0748
- 10 μl were plated on each plate
| Dilution | Colony Forming Units on Plate | Number of Cells per mL |
|---|---|---|
| 1 | Too many to count | n/a |
| 1/10 | Too many to count | n/a |
| 1/100 | Too many to count | n/a |
| 1/1000 | 190 | 19,000,000 |
| 1/10,000 | 40 | 4,000,000 |
| 1/100,000 | 23 | 23,000,000 |
| 1/1,000,000 | 6 | 600,000 |
Discussion
We have lots of cells (yay!). Cryofreezing will result in the loss cell population, but we will very likely still have viable cells after thawing.
