Migration of plasmids containing gBlocks digestion

By Léa and Alice

Products of the digestion made the 30/06/16 were migrated on a gel (0.8% agarose) during 30 min, 100 V.

Component Volume (µL)
Digested DNA 10
Loading buffer 2

For strains containing plasmids with gBlocks 4.1, according to the digestion products, 2 clones had the plasmid with the good insert. Indeed we could observe on the gel, the two fragments expected (2.7 and 0.7 Kb). All the same for strains containing gBlocks 4.2 and GFP 1-9, 3 and 2 clones respectively were good. However, DNA concentration is too low. For others strains, migration products did not get consistent results, probably due to errors during the extraction.
