genomic integration failed
pick colony from BAP1-pKD46 plate from 2013-06-04, grow in 3 ml LB+Amp at 30°C

2013-06-26

inoculate 50 ml LB + Amp + Ara(0.5%) with 1.1 ml of ON culture
grow at 30°C to OD=0.73, prepare electrocompetent BAP1-pKD46

no product -> repeat PCR with cycler 2 (fully functional)
no product -> run 2-step PCR with 4 ng pLF03 (0.2 µl of 21 ng/µl miniPrep from 2013-06-11) with primers IK07 and IK08 using Phusion polymerase (20 µl total volume, using hot start) on cycler 2:

Gel electrophoresis of the PCR amplificate. Lane 1: NEB 2-log ladder; lanes 2-5: 1 µl of PCR amplificate

load 1 µl of PCR product on gel -> specific amplificate
pool products (also include amplificate from 2013-06-28), purify (only first step, as no DpnI available)
