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

Worked as expected.
The samples were incubated for 1.5 h at 37° C.
All expected fragments were present. The relevant fragments were cut from the gel and then purified via “Qiagen Gel Extraction Kit” (Qiagen, Düsseldorf).
The samples were incubated overnight at room temperature.
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.
4 colonies of pSB1A3-iBB395146 and 4 colonies of pSB1A3-iBB496315 were inoculated in 5 ml LB medium containing ampicillin.
The plasmids were isolated with the “QIAprep Spin Miniprep Kit” (Qiagen, Düsseldorf) according to the producer instructions.
4 colonies of pSB1C3-iBB4+iBB10+iBB9 and 4 colonies of pSB1C3-iBB4+iBB13+iBB9 were inoculated in 5 ml LB medium containing chloramphenicol.
The samples were incubated for 2h at 16 °C.
The chemo competent E. coli DH5α cells were transformed with the plasmids pSB1A3-iBB4+iBB11+iBB96315 and pSB1A3-iBB4+iBB12+iBB96315 DNA and plated on LB-Amp-plates. The plates were incubated over night at 37° C.
8 new sequencing samples were sent out.
Two samples of each plasmid preparation showed the expected fragments.
4 colonies of pSB1A3-iBB4+iBB11+iBB96315 and 4 colonies of pSB1A3-iBB4+iBB12+iBB96315 were inoculated in 5 ml LB medium containing chloramphenicol.
For making new aliquots of E. coli DH5α cells 50 ml LB medium were inoculated with 500 µl of an E. coli DH5α culture.
Resulting in the plasmids pSB1A3-iBB4+iBB10+iBB96315 and pSB1A3-iBB4+iBB13+iBB96315.
Most of the preparations resulted in the expected fragments, all others were discarded.
About 80 new aliquots were made.
Obviously the wrong plasmid was sent out for sequencing. Due to the lack of enough plasmids for an additional sequence analysis, we will redo a new miniprep.
The chemo competent E. coli DH5α cells were transformed with the plasmids pSB1A3-iBB4+iBB10+iBB96315 and pSB1A3-iBB4+iBB13+iBB96315 and plated on LB-Amp-plates. The plates were incubated over night at 37° C.
4 colonies of pSB1A3-iBB4+iBB10+iBB96315 and the only single colony of pSB1A3-iBB4+iBB13+iBB96315 were inoculated in 5 ml LB medium containing chloramphenicol. Additionally the remaining ligation preparation was transformed in E. coli DH5α.
