Ag43, dT

Digestion

Results of digestion in 15th.

Digestion result image

Product:Ag43(K346007)=3120bp and 2070bp, pT7-RBS on pSB1K3=2247bp We confirmed there are some kind of restriction enzyme site in K346007 (digested with SpeI, PstI) and pT7-RBS on pSB1K3 was successfully digested with EcoRI and PstI. Balance between d+(EcoRI) and d+(E&P:cut with EcoRI and PstI) is about 80bp.


Gel Extraction

Gel Extraction for digestion products. We used FastGene Gel&PCR extraction kit(NipponGenetics). Got 50ul of DNA solution.


Ethanol Precipitation

Ethanol Precipitation for digestion and gel extraction products.

  1. Added 5ul of NaoAc, 1.5ul of glycogen and 125ul of 100% ethanol.
  2. Centrifuged in 15000rpm, 10min at 4C.
  3. Remove supernatant and added 220ul of 70% ethanol.
  4. Centrifuged in 15000rpm, 10min at 4C.
  5. Remove supernatant and air drying in room temperature then added 5ul of DW.

dT(B0015) would be amplified incorrectly and couldn't get enough digestion product. So we tried another DNA amplification method: PCR then digested.

PCR

PCR for dT(B0015)

DNA solution 1ul
KOD-Plus-NEO(Taq polymerase) 1ul
dNTP 5ul
MgSO4 3ul
KOD-Plus-NEO Buffer 5ul
Forward Primer(100bp_up forward primer) 1ul
Reverse Primer(200bp_down Reverse primer) 1ul
DW 33ul
Total 50ul


Number Degree Second
1 94 120
2 98 10
3 58 30
4 68 30
5 4 HOLD

Cycle:2~4 x 45


PCR result image

We migrated B0015 mini-prep psoduct, digestion product, and PCR product. PCRed dT would have 429bp(100bp(added by forward primer) + 129bp(dT) + 200bp(added by reverse primer)). Most bright and thick band in this image has about 300~400 bp. We thought dT was amplified successfully.

Digestion

Digestion for dT which amplified with PCR. Digested with XbaI and PstI.

dT

DNA solution 5ul
XbaI 1ul
PstI 1ul
10xM buffer 2ul
DW 11ul
Total 20ul



Ag43

Digestion result of Ag43 was incorrect. We digested Ag43 once more time.

Digestion

Digestion for Ag43 with SpeI and PstI.

Ag43 DNA solution 9ul
SpeI 1ul
PstI 1ul
10xH buffer 2ul
DW 7ul
Total 20ul


Digestion result image

There are same results with digestion result of recent. What is this 500bp fragment????


Gel extraction

Gel Extraction for digestion products. We used FastGene Gel&PCR extraction kit(NipponGenetics). Got 50ul of DNA solution.


Liquid Culture

Liquid culture for single colony isolated pT7-RBS on pSB1C3 and Ag43-dT on pSB1T3.

  1. Picked up one colony from single colony isolated plates by platinum loop.
  2. Dipped into 2ml of LBC and LBT.
  3. Cultivated.

Ag43-dT on pSB1T3 and pT7-RBS on pSB1C3

Mini-prep

Mini-prep for liquid culture products cultivated from yesterday(16th). We used FastGene Plasmid Mini Kit(Nippon Genetics) and got 50ul of DNA solutions.

Erectrophoresis

Erectrophoresis to determine bp and concentration of DNA solutions mini-prep products.

  1. Added 5ul of EtBr
