Restriction digest 1h, 37°C (10µL of minipreped DNA) As none of the transformations worked, we want to make sure which step was faulty. We're checking if all of our restriction enzymes work properly.
 * E0240 - SpeI
 * E0240 - PstI
 * E0240 - EcoRI
 * E0240 - XbaI
 * E0240 - XbaI+PstI from 13/07
 * E0240 - SpeI+PstI

Gel electrophoresis (agarose 1,0% w/v, EtB) (verification of the restriction enzymes' activity and the presence of DNA in the gel extraction sample)

Protocol (8 wells) Migration : 50V, 1h00 All the enzymes seem to work correctly. Our problem is probably the DNA yield after all the steps : not enough DNA extracted by minipreps -> no DNA visible by electrophoresis after gel extraction !
 * 10 µL of ladder 1Kb
 * 7,5 µL of undigested plasmid (E0240) + 1,5 µL of loading buffer 6x
 * 7,5 µL of digested DNA (E0240 - SpeI) + 1,5 µL of loading buffer 6x
 * 7,5 µL of digested DNA (E0240 - PstI) + 1,5 µL of loading buffer 6x
 * 7,5 µL of digested DNA (E0240 - EcoRI) + 1,5 µL of loading buffer 6x
 * 7,5 µL of digested DNA (E0240 - XbaI) + 1,5 µL of loading buffer 6x
 * 7,5 µL of digested DNA (E0240 - XbaI+PstI) + 1,5 µL of loading buffer 6x
 * 7,5 µL of digested DNA (E0240 - SpeI+PstI) + 1,5 µL of loading buffer 6x
 * 7,5 µL of gel extraction DNA (E0240 - XbaI+PstI) + 1,5 µL of loading buffer 6x
