Notebook

11.11.2011

Überschrift
Investigator: X,Y
Aim: We attempt to get results.

Wichtig ist, dass immer die verwendete Materialien (Plasmide, genomische DNA [aus welchen Stamm], Primer) genau benannt und/oder ggf. irgendwo nummeriert werden. Es sollte alles nachvollziehbar sein, wann ihr mit welchen Proben was gemacht habt.

Auf den folgenden Seiten sind Beispiele, wie wir uns das Notebook vom Aufbau und Detailgrad vorstellen.

  • 3 µl 10x T4 DNA ligase buffer
  • 2 µl T4 DNA ligase

The samples were incubated for 14 h at 18° C.

Digest

  • 1 µl HindIII
  • 1,5 µl 10x red buffer
  • 1,5 µl 10x orange g loading buffer
  • 6 µl H2O

The samples were incubated for 4 h at 37° C.

Gel electrophoresis
Gel

Gel substances

  • 1% Agarose gel
  • 10 µl RedSafe in 50 ml gel
  • 6 µl GeneRuler™ 1kb plus DNA Ladder (Thermo Scientific)

Lane   Content   Expectations
1   pSB1C3 cutted with XbaI + HindIII   2345 bp
2   pSB1C3 cutted with XbaI + HindIII   4643 bp
3   pSB1C3 cutted with XbaI + HindIII   2548 bp

We don’t receive all expected fragments.

We don’t receive all expected fragments. The expected fragment in lane 1 is missing.

Transformation
Investigator: Franzi, Christian
Aim: Transformation of the plasmid DNA pB201-40JO in E. coli for amplification.

The chemo competent E. coli DH5a cells were transformed with pB201-40JO DNA and plated on dYT-Amp-plates.
The plates were incubated over night at 37° C .

Gel electrophoresis
gel-electrophoresis-image

Gel substances

  • 1% Agarose gel
  • 10 µl RedSafe in 50 ml gel
  • 6 µl GeneRuler™ 1kb plus DNA Ladder (Thermo Scientific)

Expactations

  • Lane 1: 5300 kbp
  • Lane 2: 3300 kbp
  • Lane 3: 1300 kbp

All expected fragments were present. The relevant fragments were cut from the gel and then purified via “Qiagen Gel Extraction Kit” (Qiagen, Düsseldorf).
Inoculation
Investigator: Dominik
Aim: inoculation of colonies for plasmid preparation

4 colonies of pSB1A3-iBB395146 and 4 colonies of pSB1A3-iBB496315 were inoculated in 5 ml LB medium containing ampicillin.

Sequencing
Investigator: Dominik
Aim: Complete sequencing of pSB1A3-iBB496315.

8 new sequencing samples were sent out.

Competent cells
Investigator: Dominik
Aim: Overnight culture for making new aliquots of competent cells.

For making new aliquots of E. coli DH5α cells 50 ml LB medium were inoculated with 500 µl of an E. coli DH5α culture.
