Since the Trp-mutated strains which contained only one plasmid still managed to grow in our media even though there was a double antibiotic selection, we wondered whether they contained an antibiotic resistance which we didn't know of. To verifiy this, we put all three strains in culture either in LB+ampicilin or in LB+kanamycin. In theory only one of the strains (JW 4356-2) should grow, in the medium with kanamycin.

Here the 2nd strains seems to have a double transformant. But we let the gel overnight so there is no BrEth any more, we had to take a time of exposure of 38.2 s to see something. We will do a nicer gel this afternoon.

Since the Trp-mutated strains which contained only one plasmid still managed to grow in our media even though there was a double antibiotic selection, we wondered whether they contained an antibiotic resistance which we didn't know of. To verifiy this, we put all three strains in culture either in LB+ampicilin or in LB+kanamycin. In theory only one of the strains (JW 4356-2) should grow, in the medium with kanamycin. The other 2 strains (JRG 465 and LRG 1046) shouldn't be able to grow at all. We will check tomorrow morning.
