Progress of parts

[edit] Blue Light Receptor

[edit] Vanillin Production

1)

  • EF colonies present! So, we took 1ml off for further growth and miniprepped the remaining 4ml in triple
  • Nanodrop concentrations:
Part concentration (ng/μl) 260/280 λ
EF A 74,9 1,89
EF B 63,1 1,87
EF C 53,9 1,90
  • We performed a digest with EcoRI and SpeI to cut out the insert and check it's length. Enzymes were added separately, with 1h in between. Total volume was 30µl.
  • Calculations restriction
Part µl DNA µl MQ
EF C 9,3 20,7
  • In the afternoon, the remaining 1ml was re-plated and put on 37°C


2)

  • Test 1: Results from yesterday's restriction test were inconclusive, because the DNA ladder didn't run properly so the length of the fragments couldn't be read. Therefore, we did it again...
  • Restriction=OK! Test 1 completed.


3)

  • Test 2: cutting with 2 enzymes subsequently (1h incubation in between) in a volume of 30µl. Using a larger volume should dilute the glycerol, which inhibits cutting. After that, the products are incubated overnight to allow full restriction. sam8 and fcs are cut with EcoRI and SpeI; sam5 and ech are cut with EcoRI and XbaI
  • Calculations restriction
Part µl DNA µl MQ
Sam8 B 7,9 22,1
Sam5 B 4,0 26,0
Ech B 5,2 24,8
Fcs B 4,4 25,6

[edit] Vanillin Receptor

  • Restriction digest of X, Y and with EcoR1 and Pst1
  • Gelelectrophoresis to check fragments and gelextraction
  • Fluid medium from outplated cells (overgrowth)
  • TOPO-cloning (with new protocol from Invitrogen) for W and Z
