''Notes:'' We made four tupes with 300ul MG1655 cell media instead of 200ul. In tupe 1 and 2 I unfortunately added 800ul un-diluted precipitation solution, in tupe 3 and 4 I diluted the precipitation solution according to the GP1.1 protocol. <br><br>

''Notes:'' We made four tubes with 300 microlitres of ''E. coli'' MG1655 cell media instead of 200 microlitres. In tube 1 and 2 we unfortunately added 800 microlitres un-diluted precipitation solution, in tube 3 and 4 we diluted the precipitation solution according to the GP1.1 protocol. <br><br>

''Results:'' The concentration of the purified DNA was measured by Nano Drop. Tybe 1 and 2 did not contain any DNA wich we had expected because of the high concentration of precipitation soultion. The DNA concentration i tube 3 and 4 were 28,38ng/uL and 19,4ng/uL, respectively. Tube 3 and 4 were efterwards pooled and saved in the freezer (labeled with white tag 1) The purified DNA was run on a agarose gel to check if it actual contains DNA.
