Transformation of Adh2 z, evaluation of competence

kontinued since yesterday

So, it's official, our competent cells are really quite incompetent! Tested against the new bath of competent DH5alfa which got 220 transformations (100*10^6 / µg pUC 19)our perfored extremly bad at around 20 transformations.

We will make new CCMB80 (unauotclaved this time) and also consider to switch cells to TOP10 instead.

Plasmid prep contiued

Yesterday we performed a plasmid prep on all transformed genes. Today I did the same for the B0034 RBS. This with a small screw up as I accedentilly eluted with 1 M Tris-HCl as opposed to 5 mM! I precipitated the DNA wizh ethanol and resuspen in 5 mM Tris-HCl.

Left to do: Measure DNA koncentration for all the plasmid preps.
