Research Notebook

Week 8 (12/7 - 18/7)

▪ July 13

Anaerobic Promoter    ☀ Yi Han & Yun Ting ☀

Ligation for FNRgfp (4X)
200ng of gfp plasmid (4.36ul)
297.5 ng insert (7:1) 10.3
1ul 10Buffer (53.34)
4ul T4 ligase

Trial run of anaerobe chamber
open sachet to decrease O2 at 3.30pm
takes 2.5h to activate
streak plate of P. putida a strict aerobe and E. coli, facultative aerobe in chamber at 30deg C to grow O/N
P. putida is an obligate aerobe and if chamber works ,it will not grow
E. coli should grow in both conditions
controls grown outside chamber


▪ July 14

Anaerobic Promoter    Invasin + Listerolysin
☀ Yi Han ☀

No colonies for FNRgfp plasmid
Inv Plasmid Verification
buffer 1
EcoRI 0.5
in plasmid 0.5
dH2O 8
Total 10ul


Gel extraction RE digest of EsaR-GFP plasmid
LigationControl
Vector (45ng) 1 1
insert 1 1
Buffer 1 1
dH2O 6 7
ligase 1 1


Transformation of FNRgfp
Anaerobe jar
E. coli grew in both conditions
P putida-> some growth in anaerobe chamber
Proper streak plate in aerobic conditions
Packet runs out after 16 hours


▪ July 15

Anaerobic Promoter    ☀ Yi Han ☀

FNRgfp-> no colonies after transformation
religation (4X reaction)
200ng of gfp plasmid (4.4ul)
2125ng of insert (8ul)
4ul T4 ligase
55.6 H2O


Anaerobic Promoter    ☀ Yi Han & Chi Yan ☀

Transformation of FNR gfp into 20ul of BL21


▪ July 16

Anaerobic Promoter    ☀ Yi Han ☀

No colonies grew
Ran a gel, FNRgfp pcr, gfp pcr, fnr, 100bp ladder
▶ Seems to be band shift.


▪ July 17

Anaerobic Promoter    ☀ Chi Yan ☀

RE digest of FNR-GFP fusion PCR with EcoRI and PstI
EcoRI 1
PstI 1
Buffer 5
FNR-GFP from 12/7 in RIP box 1ug -> 2.5ul
H2O 40.5
Total 50
▶ RE for 2 hours at 37 degrees
▶ Direct purification using Promega kit

Overnight ligation (4X reaction)
200ng of gfp plasmid (4.4ul)
400ng of insert (5:1) (4ul)
4ul T4 ligase
8ul T4 ligase buffer
44.1 H2O
