Characterization of DelH Plasmid pHM04 30-08 Clones 4, 7, 15

Colony-PCR Conditions CP.W20.A

Because the sequenced DelH-colonies 4, 7, 15 had different kinds of mutations (Deletion of one basepair but also an insertion of a whole sequence part => results are shwon in week 19) we made a new screening PCR of 30 new picked colonies named 31-60 of the plate 2 of the electroporated cells realized in week 19.
There were 30 colonies screened.

Sequencing

The colonies 33, 39, 40, 46, 51, 58 were sent in MWG for sequencing. There for we prepared 15 µl of the plasmid (midiprep) with a concentration of 50-100 ng/µl and add 2 µl DN07 primer (10µM).

=> The next step is a test restriction digest with PvuI

Test Restriction Digest

We performed a test digest with PvuI-HF of the screened samples which showed a postive band at 663 bp in the screening PCR. Therefore we prepared a Master Mix with:

Enzyme	CutSmartBuffer [µl]	ddH₂O [µl]	Total amount [µl]
45x 0.5 µl = 22.5 µl	45x 2 µl = 90 µl	45x 16.5 µl = 742.5 µl	45x 19 µl = 855 µl

Incubation time: 1:20 h at 37 °C

Result

Expected bands: 11.5 Kb, 8.5 Kb and 2.6 Kb.

Some colonies showed the expected bands (see table below).

=> These are sent in for sequencing after a miniprep.

The table below shows the result of the restriction digest of different colonies containing the pHM04 plasmid. The restriction digest was positive if the expected bands were pesent.

Because the colony 6B is possibly positive, the next steps are:

1. SDS-PAGE

2. Sequencing over gibson-assembled parts

3. Triple electroporation with the plasmig of Del-rest and MalonylCoA (see lab book Delftibactin)

Very weak amplification, Primer-Dimers/Oligomers, carry over of Backbone pSB6A1 (including mRFP and therefore creating a double band, since template is 700bp longer than expected PCR product).

=> Repeat PCR with less stringent conditions to increase yield until unexpected bands appear or yield is high enough and reduce amount of template DNA (use 0.5 µL of a 1:10 delution)

=>Furthermore, elongation time was reduced, as template is only about 4.4 Kb long instead of the putative 7 Kb.

-Again, the screening-PCRs resulted in many positive colonies. After the restriction digest, many colonies were kicked out. The remaining minipreped colonies were sent in for sequencing.
