Mutation of FT
by Sato
FT gene has two BioBrick restriction enzyme sites, EcoR1 and Pst1 which is next to each other.
So we tried to delete both at once by using two primers with mutation.

Cells were stored on ice for 30min.
After 42℃ 60sec heat shock, cells were stored on ice for 2min.
Then cells were precultureed at 37℃ for 1hr, plated to Kanamycin plate.

by Sato
To check wheter mutation was succeed, we did restriction enzyme digestion.

We did electrophoresis of three FT plasmids, non-cutted, EcoR1 cutted, Pst1 cutted.
However, we couldn't get any bands (data not shown.)

We couldn't get enough concentration of plasmids.
Electrophoresis
by Sato
We retried electrophoresis of three samples same as yesterday.
However, we couldn't get any bands as well.

We decided to do PCR using FT specific primers before mutation.
