Started a regular PCR for (re-doing this genes from scratch):

Mm: six3/6
Tt: piwia, engrailed, distal-less, gli, nk6, smoothened, wnt7

Tt bands were not good, so trying a re-PCR overnight.

In the end the re-PCR did not worked well, so I purified the DNA directly forĀ  Mm six3/6 and Tt piwia, nk6, and smoothened. Ligation was set for these and let over the weekend.

Heatshock transformation and plating at 18h.

Colony PCR and selected colonies to grow at 17h30. Tt gli is being grown from Katrine’s plate. Bands were kind of variable… do not like this; let’s see if it is contamination.

Set a sequencing PCR at 11:40; delivered at 19:45.

Many Wnts mixed with the proper genes again… Interestingly, Gli samples, which I prepared the minipreps directly from Katrine’s plate did not have Wnts. This indicates that the contamination event happened afterwards, possibly during Henrike’s stay. It seems that something in the ligation kit is the culprit.
