July 29 (Thu)
Attendance: Torigata, Takino, Teoh, Yasumoto, Kakuda, Saka, Tamura
- Safety lecture for junior members.
- Preparation of LB agar plates (26 Amp, 25 Kan, 25 Cam).
July 31 (Thu)
Attendance: Miyatake, Hirayama, Torigata, Teoh, Tadashi, Yasumoto, Kakuda, Saka
- Meeting
- Summer project schedule
- List of genes to clone
August 2 (Mon)
Attendance: Torigata, Takino, Teoh, Tadashi, Yasumoto, Saka
- Culture medium preparation
- LB agar plates (49 antibiotic-less plates)
- LB liquid medium (500 ml)
- Competent cells preparation - Nojima Method
- SOB medium (MgCl2 not yet added) -> stored at 4˚C
- TB buffer -> stored at 4˚C
- Single-colony streaking of E. coli (strain DH5α) on 2 LB agar plates -> 37˚C incubation o/n
Tomorrow we shall prepare the remainder of the reagents and inoculate SOB with o/n-incubated E. coli.
August 3 (Tue)
Attendance: Nakamura, Kakuda, Saka, Yasumoto, Teoh
- Competent cells preparation (continued)
- Preparation of glucose solution for making SOC medium.
- Inoculation of pre-culture SOB from o/n-incubated agar plate colonies.
- (Night) Transfer from pre-culture to growth culture.
August 4 (Wed)
Attendance: Nakamura, Saka, Kakuda, Yasumoto, Torigata, Teoh
- OD measurements throughout the day till required OD (0.3~0.7) was obtained.
- Completion of competent cells according to protocol.
August 5 (Thu)
Attendance: Nakamura, Yasumoto, Saka, Kakuda, Takino
- Transformation of Registry parts:
ID | Part Name | Resistance | Description |
---|---|---|---|
2-20J | <bbpart>BBa_K118023</bbpart> | A | C. fermi endocellulase Cen A coding |
2-20H | <bbpart>BBa_K118022</bbpart> | A | C. fermi exocellulase Cex coding |
1-2M | <bbpart>BBa_B0034</bbpart> | A | RBS |
1-13D | <bbpart>BBa_B0010</bbpart> | A | terminator |
1-1D | <bbpart>BBa_R0010</bbpart> | A | promoter |
1-18F | <bbpart>BBa_E1010</bbpart> | K | RFP coding |
Note: 'ID' is an internal identifier used by wet work members to simplify labeling etc. In the case of iGEM distribution parts it usually refers to the plate location.
August 6 (Fri)
Attendance: Nakamura, Saka, Yasumoto, Takino, Teoh
- Colony check
- All transformed cells produced colonies!
- Non-transformed cells (negative controls) did not grow on Amp, Kan or Cam plates -> confirmed lack of natural antibiotic resistance
- Colonies transferred to LB growth medium & incubated o/n at 37˚C
August 7 (Sat)
Attendance: Nakamura, Saka, Yasumoto, Takino
- Miniprep
- Transformation of construction plasmids
ID | Part Name | Resistance | Description |
---|---|---|---|
1-1C | <bbpart>pSB1A3</bbpart> | A | construction plasmid containing mRFP coding device (<bbpart>BBa_J04450</bbpart>) |
1-3A | <bbpart>pSB1C3</bbpart> | C | (" ") |
1-5A | <bbpart>pSB1K3</bbpart> | K | (" ") |
- Meeting
August 8 (Sun)
Attendance: Nakamura, Yasumoto
- Colony check
- All parts successfully transformed
- Transfer to liquid culture medium
August 9 (Mon)
- Miniprep of 1-1C
- Restriction digests of 2-20H, 2-20J, 1-1D, 1-18F, 1-1C, 1-13D, 1-2M
- Transfer of 1-3A, 1-5A colonies to solution culture (repeat)
- Yesterday's inoculated culture mediums contained the wrong antibiotics!
- Transformation of <bbpart>BBa_I13521</bbpart>, <bbpart>BBa_I13522</bbpart>, <bbpart>BBa_I13600</bbpart>, <bbpart>BBa_K204031</bbpart>, <bbpart>BBa_K204051</bbpart>, <bbpart>BBa_K204032</bbpart> from last year's stock
August 10 (Tue)
- Miniprep of 1-3A, 1-5A
- Restriction digests of 1-3A, 1-5A
- Gel electrophoresis (twice)
August 11 (Wed)
- Miniprep of last year's parts transformed on Monday
- Gel electrophoresis of 1-1D, 1-18F, 1-13D, 1-2M
- all 4 plasmids could not be cut... AGAIN
- so far all restriction digests involving XbaI seem to have failed; problem with our enzyme?
- will try with different set of restriction enzymes next week
