AUGUST: WEEK 4



August, 23rd

Colony PCR as screening for ligations I31..I41. For each plate three colonies were picked and PCR amplification was performed. At the same time colonies were let grow in 750 ml LB+Amp in order to be ready to make glycerol stocks for those with right amplicons.

Colony PCR and gel run as screening for ligations I31..I41

Only I31, I33, I34, I35, I37, I38, I41 are positive without any doubt (we took I31-1, I33-1. I34-1, I35-1, I37-1, I38-3, I41-1), while I39 were all wrong and we weren't sure about I32, I36 and I40 (we made however glycerol stocks for I32-2, I36-2, I40-1). We decided to repeat colony PCR for I32, I36, I39 and I40 next day.


August, 24th

Only this morning we remembered that I40 is in a commercial vector (pMA), we will screen it next day through an E-P digest (today we made glycerol stocks for other four colonies: I40-4/5/6/7) since it isn't possible with colony PCR.

With this method we checked four new colonies of I32 (I32-4/5/6/7), I36 (I36-4/5/6/7) and I39 (I39/4/5/6/7).

Colony PCR and gel run as screening for ligations I32, I36, I39

I39-4/5 are right (we made glycerol stock for I39-5); I32 and I36 still show the presence of cotrasformation of our ligation and a simple phasin (we took I36-7 instead of I36-2: cleaner gel run). We inoculated 5ml LB+Amp with I40-1/4/5/6/7 and we let them grow at 37°C, 220 rpm for E-P digestion/screening.
