ColiGuard

PCR colony of the BBa B0014 + BBa K112806 Ligation

• We chose 9 colonies to do the PCR, 3 results were positive, the colonies 2, 5 and 7 and appeared in the agarose gel with the expected size! 2 colonies was used to do a innoculum that will be used in a miniprep tomorrow

finOP-pGEM digestion purification

• After confirming correctly finOP with pGEM ligations, today we gather all confirmed samples (for finO and for finP) into a single sample for each one.
• We ran 40 uL of each gathered sample in an agarose gel for later purification. Unfortunately, finP band appeared extremely weak in the gel and we weren't able to purify it. As for finO, it's band appeared in gel, but we decided to wait for finP in order to perform both purifications together.
• Thus, we took all the gathered finP sample left and concentrated it in speed vacuum, until ir reaches about 20 uL. Then we ran another agarose gel with this concentrated sample and with another 40 uL from finO gathered sample.
• This time, finP appeared as a barely visible band, but we were able to purify it, as we did for finO to.
• We performed purification using Invitrogen's Purelink Quick Gel Extractin Kit, following manufacturer's protocol (Protocol 7) without modifications).

finOP purification results

• After purification procedure, we quantified total DNA present in both samples.
• finO resulted in 15 ng/uL. Although very low, this amount might be enough for proceeding in biobrick construction.
• As for finP, no amount could be measured. =/ Probably, the barely visible band hadn't enough DNA for detection or there was a significant loss during purification process.

finO

• Even with no longer finP available, we continued finO's work by ligating finO purified sample into biofusion digested vector, according to Protocol 11.
• We then dialyzed the ligation product for 20 minutes and transformed them into electrocompetent E. coli bacteria, strain DH10B, according to Protocol 3.
• After one hour being incubated at 37 ºC, transformed cells were plated into LB-AMP media.
• Plates were incubated at 37 ºC for an O/N period.

YeastGuard

pADH1+YFP (new biobrick)

• The colonies grew up very well in the plates. So, we selected ten colonies to grow in liquid ?meio? O/N.

YEP vector

• Purification of the bands that correspond to the YEP size digested with PvuII. Then we recirculamos the YEP trough a ligation reaction.
