- Transformation of the single deletions strains E. coli strains KRX ∆alr and DH5alpha ∆alr with the plasmid pRedET containg the Recombinase using the Genebridge RedET-System protocol.
- Successful amplifikation of the oligonucleotide containing the flanking sites for the deletion of dadX and purification using the gel extraction clean-up kit from Promega.
-
Transformation of the oligonucleotide containing the flanking sites for the deletion of dadX. The successful replacement of the constitutive alanine racemase was verified via kanamycin selection and
Colony PCR (dadX_Ec_control1, dadX_Ec_control2)
- Annealing temperature: 55 °C
- Bands as expected (3004 bp)
- Resulting in the genotype DH5aplha ∆alr kan:dadX, while the dadX deletion in the KRX strain was not successful.
