Aim: Transformation of E. coli DH5α with the plasmid DNA pSB1A3-iBB10+iBB9, pSB1A3-iBB11+iBB9, pSB1A3-iBB12+iBB9 and pSB1A3-iBB13+iBB9.

The chemo competent E. coli DH5α cells were transformed with the plasmids pSB1A3-iBB10+iBB9, pSB1A3-iBB11+iBB9,pSB1A3-iBB12+iBB9 and pSB1A3-iBB13+iBB9 DNA and plated on LB-Amp-plates.
The plates were incubated over night at 37° C.

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.

Digest
Investigator: Alex
Aim: Digest of pSB1A3-iBB395416 and pSB1A3-iBB496315 with EcoRI and PstI.
  • 1 µl Plasmid DNA
  • 0.3 µl EcoRI
  • 0.3 µl PstI
  • 1 µl Cut Smart
  • 7.4 µl ddH2O

The samples were incubated for 2 h at 37° C.

Gel electrophoresis
gel-electrophoresis-image

Gel substances

  • 1% Agarose gel
  • 10 µl Ethidium bromide in 50 ml gel
  • 4 µl 2-log DNA ladder

Expectations (upper gel)

  • Lane 2-5: 2,400 + 2,000 bp
  • Lane 6: 1,000 + 2,000 bp
  • Lane 7: 1,400 + 2,000 bp

Expectations (lower gel)

  • Lane 2-7: 2,400 + 2,000 bp
  • Lane 8: 1,200 + 2,000 bp

All clones show a double band above 2,000 bp.

We received all expected fragments. The success of the ligation should be double-checked by means of PCR.
