Miniprep of 7/15 Cultures
- I miniprepped each of the five samples of Silk in Pet 24a using the Zymo Miniprep kit.
OD:
- 95.98ng/uL
- 108.12ng/uL
- 88.05ng/uL
- 128.87ng/uL
- 99.23ng/uL
Colony PCR of 7/15 Transformation
Transformation Results
Each plate only had one colony present. Both were picked and suspended in 100uL Nuclease Free Water.
Colony PCR Reaction
- using Q5, transformed E. coli, and the VF2 and VR primers in preparation for insertion into psb1c3
- Two reactions, one for each of the colonies.

5X Q5 Reaction Buffer | 5uL |
10mM dNTPS | 0.5uL |
10mM VF2 primer | 1.25uL |
10mM VR primer | 1.25uL |
Transformed cells in ddH2O | 1uL |
Q5 High Fidelity DNA Polymerase | 0.25uL |
Nuclease Free Water | 15.75uL |
Step | Temperature | Time |

Initial Denaturation | 98C | 3 min |
Cycles (x25) | 98C | 10s |
Annealing | 66C | 15s |
Extension | 72C | 15s |
Final Extension | 72C | 2min |

- TM calculated using NEB TM Calculator
- Total Run Time 35 minutes (including ramp times)
Gel Visualization
Both samples were run on a 1.5% agarose gel against a 1kb ladder.
Expected band size: ~1600bp
Results:
Re-do of Silk-SpyCatcher Transformation
- There were only one or two very small colonies from our transformation on 7/15.
- We will colony PCR these two colonies
- We will also re-try the ligation of the silk+SpyC into the psb1c3 backbone, this time cleaning up the ligation using zymo clean and concentrator and eluting into 10 ul of H20.
- We can then re try the transformation.
