1.before Min prep
Checked the cell cultures transformed and plated out yesterday (8/10) for colony formation and made an approximate count of the number of colonies.

(plate number)-(location on plate) (no. of colonies)
                       1-2M                       100~    (Amp)
                       2-24G                      1?
                       1-12C                      10
                       1-6I                       10<
                       2-8I                       10<
                       2-6E                       10<
                       1-16G                      10
                       1-12A                      10<    
                       2-8O                       10< 
                       
                       2-11N                       10    (Kan)
                       1-18L                       50   

 inoculate to iquid medium(5mL + Amp 5uL or Kan 25uL)

after  ligation
              EpsE + terminator                    3        →  liquid medium
             RBS   +  LasR(2-8M)                 10     → rapid check

2.digestion and ligation
