*[[Melbourne/Diagnostic Digest| Digested]] and [[Melbourne/Loading a DNA gel|Ran on a Gel]] [[Melbourne/M30109| M30109]] minipreps from 25/8 using a number of restriction enzymes to try to find out what it is:

The results showed that although a fragment of cph8 may be present in the part (1200bp fragment present only when double digested by EcoRV/Xho1), it may not be in the form as designated in the iGEM wiki.
 +
 +
The original miniprep was sent off for sequencing using [[Melbourne/primary vf2|vf2]]. The results showed that the part is a form of RBS-cph8, although the sequencing got cut off in the middle of the cp8 sequence. Therefore, the entire part designated is not present. We consequently decided to create the [[Melbourne/M30109| M30109]] part ourselves.

Week 9

19 Aug 2007

  • Picked 3-4 transformants from "ligation" plates (17/8) and Grew up liquid cultures.
  • Transformed the two ligation reactions in the pink rack in the cold room and plated on Gen + Amp plate.


20 Aug 2007

Desired products:

    1. 450bp (95bp different from CI-2 used as control)
    2. 450bp
    3. 450bp
    4. 1kb
    5. 1kb
  • These were run on a gel.


OmpR-inverter
-Vector: OmpR (AmpR) miniprepped P1 15P from 10/7 digested with S/P.
-Insert: c1 inverter (1kb fragment) P2 13K A with X/P.


RBS-LacZ
-Vector: LacZ (KanR) P2 9E from 6/8 with E/X.
-Insert: RBS (GenR) P4 8J from 6/7 with E/S.


Digested for 2h and heat inactivated for 10min at 80degC.


21 Aug 2007

  • Picked 4 colonies from fresh ligation/transformation to Growing up.

- These transformations were made as follows:

    • Ligated
      1. 5ul of Purified insert from 17/8 (CI-2 E/S)
      2. 5ul of Redigested P1 5G with E/X and heat inactivated at 60degC for 10min.


22 Aug 2007

  • Miniprepped L1-L4 (liquid cultures from 21/8).
  • Digested these for ligations.
    1. L1 X/P
    2. L2 X/P
    3. L3 X/P
    4. L4 X/P
    5. CI-2 X/P (control for 350bp)
    6. P1 15P S/P

All L1-L4 had the 450bp desired band.

  • Gel purified 450bp band from L3 and a 950bp band from the P2 13K digest.

OmpR-L3 (RBS-LacZa-double term)
-Vector= P1 15P S/P (above)
-Insert= L3 X/P (above)

OmpR-c1 inverter (P2 13K)
-Vector= P1 15P S/P (above)
-Insert= P1 15P S/P (above)

Ligations were kept overnight at 4degC.


23 Aug 2007

  • Transformed ligations from 22/8 into competent NM522 cells.


24 Aug 2007

  • Liquid cultures were made of transformations from 23/8. 6 colonies were picked from each ligation.


25 Aug 2007

  • Ran on a Gel 16 samples that were miniprepped.
  • Gel purified 1000bp fragment from ompR-c1 inverter ligation digest and a 600bp fragment from ompR-L3 ligation digest.

Week 10

26 Aug 2007

(all from 25/8) Left overnight at 4degC.


27 Aug 2007

Plated on Amp plates.


28 Aug 2007

  • Picked six colonies from each plate (27/8) and cultured at 37degC for 13 hours.


29 Aug 2007

-The M30109 ligations yielded random fragments: something wrong with the part? - P1 15P-L3 and P1 15P-c1 inverter ligations had bands of the desired size.


30 Aug 2007

  • Set up minipreps from 29/8 for sequencing.

OmpR-L3 and OmpR-c1 inverter were the desired sequences.

Parts created:

OmpR-RBS-LacZa-double terminator

OmpR-c1 inverter

Week 11

    1. EcoRV
    2. Xho1
    3. EcoRV/Xho1
    4. E/P
    5. E/S
    6. E/X
    7. X/P
    8. X/S
    9. S/P
    10. E
    11. P
    12. S
    13. EcoR1/EcoRV/Xho1
    14. Apa1
    15. BamH1
    16. EcoR1/BamH1

The results showed that although a fragment of cph8 may be present in the part (1200bp fragment present only when double digested by EcoRV/Xho1), it may not be in the form as designated in the iGEM wiki.

The original miniprep was sent off for sequencing using vf2. The results showed that the part is a form of RBS-cph8, although the sequencing got cut off in the middle of the cp8 sequence. Therefore, the entire part designated is not present. We consequently decided to create the M30109 part ourselves.

    6. OmpR-RBS-LacZa-double terminator from 29/8
    7. OmpR-RBS-LacZa-double terminator from 29/8 into CP919 EnvZ- strains.
