PMA Detection

Week 1
Take Peroxidase out of the registry.


Order MaoA in two parts, N and C terminals.

Week 2
16/06
Digest pSB1C3 (1.23O2), pSB1A3 (4.2H1) and pSB1K3 (4.6B1) with EcoRI HF and PstI. Digest MaoA N and MaoA C (EcoRI HF/PstI).
Gel purify backbones, PCR purify inserts. Nanodrop.


17/06
Ligate MaoA N 1 to pSB1C3, MaoA N 2 to pSB1K3, and MaoA C to pSB1A3. Transform.

18/06
Growth appears on all plates (except for negative control). Less growth on the plates with backbone only which indicates that some of the insert ligated into the vector. Culture 3 colonies from each plate.

19/06
Miniprep cultures. Nanodrop.


Diagnostic digest to show if inserts are actually present. pSB1K3 seems to have false positives.

Week 4
22/06

Week 5
29/06
Digest MaoA N1 1 in pSB1C3 and MaoA C 1 in pSB1A3 for fusion. PCR purify pSB1C3+MaoA N, gel purify MaoA C. Nanodrop.


Ligate pSB1C3+MaoA N to MaoA C overnight.

30/06
Transform ligation reactions.

01/07
All of the transformations appeared to have worked. Culture transformations

02/07
Miniprep cultures. Nanodrop.


Send pSB1C3+ MaoA N+MaoA C 1 and 2 for sequencing.
Run a diagnostic digest on them.
Diagnostic digest shows that MaoA N and C did not fuse, as together they should be around 2.3 kb and the insert is much smaller, closer to 1 kb which is the size of MaoA N alone.
Culture 4 more colonies from pSB1C3+MaoA N+MaoA C to see if there was successful fusion in any of them.

03/07
Miniprep the cultures. Nanodrop.


Run diagnostic digest to see if the fusion worked.

Diagnostic gel shows that the fusion did not work.

Week 6
07/07
Retry fusing MaoA together. Digest pSB1C3 +MaoA N (AgeI/SpeI) and pSB1A3+MaoA C (NgoMIV/SpeI). Treat pSB1C3+ MaoA N with Antarctic phostphatase.
Gel purify. Nanodrop.


Ligate MaoA C into pSB1C3+MaoA N.

08/07
Transform ligation results to see if MaoA fused.

09/07
No growth on plates which indicates that MaoA did not fuse.
Try fusion again by going back to the gBlock. Digest pSB1C3+MaoA N (AgeI/SpeI) and the MaoA C gBlock (NgoMIV/SpeI). Treat pSB1C3+MaoA N with Antarctic Phosphatase. Ligate the two together. Transform the ligation.

10/07
No colonies on control plates (backbone only), quite a few colonies on plates of backbone plus insert which indicates fusion of MaoA.

12/07
Inoculate colonies of transformants.

Week 7
13/07
Miniprep the two colonies with potential fusion of MaoA. Nanodrop.


Diagnostic digest the plasmids to fully ensure fusion of MaoA.
