We ressuspended biobricks BBa_E0840 (GFP device), BBa_I718017 (lox71), BBa_J61000 (chloramphenicol resistance cassette) and BBa_I718016 (lox66), and then transfomed them into electrocompetent E. coli cells, strain DH10B, according to | + | *<p style=”text-align:justify;”>We started our "new strategy" (related to modifying Paris 2007 team's biobricks) by recovering some biobricks that had now became useful for our project.

| + | * Today we repeated both Cre-Recombinase's and pSB1A3's digestion with ''Xba''I and ''Spe''I. Digestion lasted 3 hours. | ||
| + | * Then, we ran an 1% agarose gel in order to confirm that digestion actually worked. | ||
