There seems to have been a contamination or other strange issue with the S101L DNA and/or FspI enzyme. For your final reports, please use my old data, which is posted above. Unfortunately, some of the bands are faint. Lane 1 is parent IPC (only one form of the plasmid is visible), lane 2 is the ladder, lane 4 is the parent digested with FspI, and lane 8 is the S101L mutant digested with FspI. The short band is very faint, but it is present. I will have the original photo available for viewing for anyone who wants to clearly see the short band. | [[Image:S09-M1D5_S101L-cropped.tiff|right |thumb|250px | Teaching example, cropped]] | ||

TR O/N cultures and Gels
The table below lists the OD600 values of 1:10 dilutions of the cultures grown overnight, as well as the pellet observations.
Group | OD WT | OD S101L | OD Chosen mutant | Pellets yellow? |
---|---|---|---|---|
Pink | 0.117 | 0.098 | 0.126 | Yes |
Yellow | No finished samples | N/A | N/A | No |
Red | 0.121 | 0.187 | 0.133 | Yes |
Orange | No finished samples | N/A | N/A | No |
Note: 1% gels were run for 45 min, 1.2% gels for 60 min, both at 100V.
