ColiGuard

Ligation of finOP and Cre-Recombinase on pGEM vector

• In order to start our pGEM strategy on assembling biobricks, today we ligated PCR's products of finO, finP and Cre-Recombinase into pGEM Vector. There is no need for any digestion before this procedure, since pGEM has an T stick ends capable of pairing with the A stick ends left by Taq Polymerase on the PCR products.
• We followed protocol 11, without modifications.
• Ligation lasted 1 hour.

Transformation of finOP's and Cre-Recombinase's ligations

• After performing the required ligations, we then transformed them into electrocompetent E. coli bacteria, strain DH10B, according to protocol 3.
• We plated the trasformed cells in LB-AMP media, which already contained X-gal substrate.
• Plates were incubated at 37ºC for an O/N period.

New biobricks - New strategy (pGEM)

• The ligation reactions didn´t work. So today we decided not to digest the fragment and the pGEM vector with SpeI, but to ligate it directly, considering that we can confirm the correct insertion by PCR.
