September, 30th

Tecan Test Nico


Transformation of I73 (1ul) into E. coli TOP10. It was plated on LB+Amp 100 ug/ml agar plate.

Trasformation of:

  • I70 (myYeast with I4, Ptef1-mOrange-tAdh1) in TOP10 and plated on LB+Amp
  • I71 (myYeast with I1, mOrange-tAdh1) in TOP10 and plated on LB+Amp
  • I72 (pLac-RFP in pSB4C5) in TOP10 and plated on LB+Cm 12,5

All plates were incubated at 37°C ON


Since I55 was negative again we decided to ligate it again (probably we had a bad digest for vector - I20 - and a good one for insert - we used I38 in other ligations without problems). We diegested already miniprepped DNA for three hours with 1 ul of enzymes:

  • I20: (E-X)

Gel run/cut/extraction/quantification

I20 E-X digest.

I20 E-X: 13,4 ng/ul

We repeated I55 ligation using newly digested vector and already digested I38 (E-S)

I55: I38 (E-S) + I20 (E-X)

Inoculum into 5ml LB+Amp of:

  • I31
  • I35
  • I37
  • I57
  • I60
  • INTEIN
  • 3x <partinfo>BBa_J04450</partinfo> (to take <partinfo>pSB1C3</partinfo>, so <partinfo>pSB1C3</partinfo> from now on)

Cultures were let grow ON at 37°C, 220 rpm.


Inoculum of E. coli TOP10 in 1,5 ml LB, grown ON at 37°C 220 rpm. Tomorrow we will prepare competent cells!!

Inoculum of:

  • S1 in 500ul M9+Cm 12,5
  • I47-S1 in 500ul M9+Amp+Cm 12,5
  • GFP-S1 in 500ul M9+Amp+Cm 12,5
  • RBS32 in 500ul M9+Amp

Cultures were grown ON at 37°C 220 rpm.

Tomorrow we will test the ability of these str.ains to produce GFP and to lyse when HSL is added.

October, 1st

This morning, we checked tranformed plates:

  • I72 showed NO colony!! :/ we will repeat this ligation next week
  • I70 and I71 showed colonies, 5 for each plate were picked and inoculated in 1ml LB+Amp to prepare glycerol stocks and for screening.
  • I73 showed colonies; six of them were picked and inoculated into 5 ml LB+Amp and let grow ON at 37°C, 220rpm in order to do E-P screeening the following day.

Transformation of I55 into E. coli DH5-alpha. It was plated on LB+Amp 100 agar plate and let grow ON at +37°C.

PCR from colony for I55 (eleven colonies were picked).

Gel run:

I55 colony PCR screening.

We decided to make glycerol stock for I55-1. Inoculum into 5 ml LB+Amp of the positive culture that was let grow ON at 37°C, 220 rpm.


Miniprep and quantification for I73-1/2/3/4/5/6:

As you can see they are (except for I73-6) all positive. So we stocked I73-1 and stored it at -80°C.


Transformation of I74 and INTEIN_C3 (1ul) in E. coli TOP10. They were plated on LB+Amp100 and LB+Cm34 agar plates respectively. They were let grow ON at +37°C.

Miniprep and quantification of:

  • I55-1: 57,4 ng/ul
  • I55-1bis: 79,6 ng/ul

I55-1bis was digested E-S for about three hours and than gel run/cut.


Colony PCR for I74 (six colonies were picked).


Gel run for PCR samples and I55 (E-S) and cut for this one.
