Kits for Plasmid and DNA purification

DNA was extracted in small or medium scale using the Promega or Qiagen DNA preparation kits. When performing sequencing, Qiagen kits were preferred.

Oligonucleotides

Oligos were annealed and subsequently cloned into EcoRI/XbaI predigested reporter backbones. Thereby short synthetic DNA-sequences (in this case for the promoters psulA, precA and precB) can be generated in a fast and easy manner.

LB growth media - components an recipe

LB media was prepared from 10 g/l tryptone, 5 g/l yeast extract and 5 g/l NaCl and autoclaved before usage. For preparing LB agar plates, 1.5 g of agar were added to the media. The media was furthermore substituted with 100 ug/ml ampicillin (for LB-amp) or 35 ug/ul chloramphenicol (for LB-cm).
