Minipreps from BBa_E0840, BBa_I718017, BBa_J61000 and BBa_I78016

• Today we performed minipreps from yesterday's inoculated cultures, related to the biobricks already cited.

• We followed Protocol 2, without modification.

Purification of pTet and double terminator biobricks

• Once we digested those biobricks yesterday, we could proceed today to the purification of the target band from an agarose gel.

• We used Invitrogen's Purelink Quick Gel Extraction Kit, following the manufacturer's protocol (Protocol 7), without modifications.

PY Promoter - Digestion and ligation reactions

• Today we digested PY1 + pGEM with EcoRI and SpeI to excise PY fragment.

• We also digested the plasmid BBa_J23100 (that one with the RFP reporter) with EcoRI and SpeI. With this plasmid digested with this 2 enzymes it is going to be possible to insert our digested PY fragment into this plasmid.

• This digestion reactions lasted for 3 hours.

• After the digestion we performed the ligation reaction of PY1 + BBa_J23100 following Protocol 11.

Dephosphorylation - CIAP test

• The E.coli didn´t grow in any of the plates again. =[ We discovered that the electrocompetent E.coli that we used yesterday were dead! So we transformed another electrocompetent E.coli using the rest of the ligation reactions we had. We extremely hope to find colonies tomorrow!
