August 27th
Colony PCR
Colony PCR to confirm that whether the pT7-RBS-Ag43-dT on pSB1C3 was successfully ligated or not.
DNA solution | 4 ul |
Kapa-Taq(Taq polymerase) | 5 ul |
Forward Primer(ag43-f4 primer) | 0.5 ul |
Reverse Primer(200bp down primer) | 0.5 ul |
Total | 10 ul |
Number | Degree | Second |
1 | 95 | 120 |
2 | 95 | 30 |
3 | 53.0 | 30 |
4 | 72 | 60 |
5 | 72 | 60 |
6 | 4 | HOLD |
Cycle:2~4 x 35
We used N1 (DW only) and N2 (Ag43-dT on pSB1AK3) as controls. Desired product is about 695bp.

Incubation for mini-prep of pT7-RBS-Ag43-dT on pSB1C3
Incubation of pT7-RBS-Ag43-dT on pSB1C3 in LBC liquid medium.
- Prepared 2 ml LBC into culture tubes.
- Re-suspended 2 colonies (No.1 and No.2 respectively).
- Incubated at 37C for 15 hrs.
Transformation of ptet-RBS(B0034)-CFP-dT on pSB1A2
- Mixed 1 ul DNA to 50 ul of thawed competent cells on ice.
- Incubated on ice for 30 min.
- Mixed 350 ul of LB.
- Prepared and Labeled two plastic plates with LBC.
- Plated 300 ul of the culture onto first dish and spread.
- Mixed 450 ul of LB to 50 ul of the culture and plated 300 ul of it onto second dish and spread.
- Incubated the plates at 37C for 15 hours.

mini-prep of pT7-RBS-Ag43-dT on pSB1C3
Mini-prep of pT7-RBS-Ag43-dT on pSB1C3. We re-suspended No.1,2 colonies and incubated. [[image:|thumb|mini-prep result]]
Estimation of Concentration of RBS-eYFP-dT and ptetR-pSB1A2
Solution | Value(ul) |
1kb ladder | 1 |
Insert | 1 |
Vector | 1 |
[[image:|thumb|Electrophoresis result]]
From this result, We estimated that the concentration of Insert DNA solution is about 40mM, and Vector DNA is also about 40mM.
Digestion of ptet-pSB1A2 and RBS-Ag43-dT
ptet-pSB1A2(Vector) was digested with SpeI and PstI, and RBS-Ag43-dT(Insert) was cut with XbaI and PstI. Vector
DNA solution ( 40ng/ul) | 5 ul |
SpeI | 0.5 ul |
PstI | 0.5 ul |
10xH buffer | 2 ul |
DW | 12 ul |
Total | 20 ul |
Inset
DNA solution ( 40ng/ul) | 14 ul |
XbaI | 1 ul |
PstI | 1 ul |
10xM buffer | 2 ul |
DW | 2 ul |
Total | 20 ul |
Number | Degree | Minute |
1 | 37 | 180 |
2 | 60 | 15 |
3 | 4 | HOLD |
[[image:|thumb|digestion result]]
From this result, we confirmed that Insert and Vector DNA were digested.
Ethanol Precipitation
Ethanol precipitation for ptet-pSB1A2 and RBS-eYFP-dT digestion products.
- Added 5 ul of NaoAc, 1.5 ul of glycogen and 125 ul of 100% ethanol.
- Centrifuged in 15000 rpm, 15 min at 4C.
- Remove supernatant and added 220 ul of 70% ethanol.
- Centrifuged in 15000 rpm, 10 min at 4C.
- Remove supernatant and air drying in room temperature then added 10 ul of DW.
Ligation
Ligation for ptet-pSB1A2 and RBS-eYFP-dT. We used Ligation Mighty Mix (TAKARA BIO INC.) which contains ligase and buffer.
Vector DNA | 3 ul |
Insert DNA | 3 ul |
Ligation Mighty Mix | 6 ul |
Total | 12 ul |
Ligation reaction time was in detail below.
Degree | Minute |
