Analysis of the RD samples from 12.7

Analysis of the RD samples from 12.7.

Test run of plasmids purified on 12.7.13, vector and inserts on agarose gel

  • part 7 plasmid, purified on 12.7.13
  • pSB1C3 vector from part 7, purified on 11.7.13
  • plasmid RBS-GFP-Terminator C12
  • plasmid RBS-GFP-Terminator C12 test restriction with EcoRI
  • inserts of DarR/riboswitches after 2nd digest with EcoRI
  • 1% agarose-1xTAE-gel
  • 3 µl 2 log ladder loaded on both sides of gel as a marker

(for Riboswitch iGEM_41/42 and _42/43, there were too small amounts of PCR product left -> control was not possible…)

  • Run at 100 V
  • EtBr staining + destaining in water
  • UV detection

Purification of DarR and Riboswitch inserts

  • Qiagen PCR purification kit
  • 500 µl PB used for each reaction
  • 2x elution in pre-warmed HPLC water (25 µl)
  • NanoDrop concentration measurements (for some samples, the concentration was measured twice, since first values for 1st and 2nd elution were a little strange… -> approximate average concentration can be used for further calculations)

  • 1st elution
