  • 1 µl CutSmart
  • 7.4 µl ddH2O

The samples were incubated for 1 h at 37° C.

Gel electrophoresis
gel-electrophoresis-image

Gel substances

  • 1% Agarose gel
  • 10 µl RedSafe in 50 ml gel
  • x µl Hyper Ladder

Expactations

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

Worked as expected.

Investigator: Dominik
Aim: Test digest of pSB1A3-iBB4+iBB13+iBB96315 with EcoRI and PstI

  • 1 µl Plasmid (pSB1C3-iBB39,pSB1A3-iBB49 and pSB1C3-iBB6315)
  • 0.3 µl EcoRI
  • 0.3 µl PstI
  • 1 µl CutSmart
  • 7.4 µl ddH2O

The samples were incubated for 1 h at 37° C.

After that, a gel electrophoresis was made, but failed and has to be repeated the next day
Inoculation
Investigator: Dominik
Aim: inoculation of colonies for plasmid preparation

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

Sequencing
Investigator: Dominik
Aim: Examination of sequence analysis of the plasmids pSB1A3-iBB496315, pSB1A3-iBB4+iBB10+iBB96315 and pSB1A3-iBB4+iBB13+iBB96315.

  • pSB1A3-iBB496315: Okay
  • pSB1A3-iBB4+iBB10+iBB96315: mutation in signal peptide that leads to Trp → Leu. Will be ignored
  • pSB1A3-iBB4+iBB13+iBB96315: mutation in terminator, will be ignored.

All plasmids are brought to Marian who will transform them in P. tricornutum cells.
