digestion and PCR result

We did not do digestion of vector DNA sokution, result, because it has only too low concentration to be digested product solution.
We failed PCR again. The digestion result was confirmed that the Insert DNA was successfully digested by XbaI and SpeI. And we extracted the insert DNA digestion product from agarose gel by gel-extraction kit and got 20 ul of Insert DNA solution.

Digestion of pSB1AK3 by hindIII

The gel-extracted DNA solution contains Ag43-dT DNA and pSB1AK3 DNA because these DNA have same size of base pair and exist as same band in agarose gel. Thus we digest pSB1AK3 with HindIII to separate it from Ag43-dT.

  3. Removed supernatant and added 220 ul of 70% ethanol.
  4. Centrifuged at 15000 rpm, 15 min at 4C.
  5. Removed supernatant and dried out at room temperature, after that added 10 ul of DW.
ethanol precipitation result

We estimated the concentration of ethanol presipitation products.The concentration of Insert DNA solution is about 20 ng/ul and Vector DNA solution is about 37 ng/ul.

Incubation of pT7-RBS-Ag43-dT-pSB1C3 transformation product

We failed to cultivation of above construct two times so we tried to incubation in LBC liquid medium.

  1. Prepared 1.8 ml LBC into culture tubes.
  2. Re-suspended 200 ul transformation product solution (which was mixed with LB and incubated for 3 hrs).
  3. Incubated at 37C.

Ligation of eCFP and RBS-pSB1A2

Vector DNA (37 ng/ul) 1 ul
Insert DNA (20 ng/ul) 4 ul
Ligation Mighty Mix 6 ul
Total 11 ul

Transformation of eCFP-RBS-pSB1A2

  1. Mixed 2 ul eCFP-RBS-pSB1A2 ligation product to 50 ul of thawed competent cells on ice.
  2. Incubated on ice for 30 min.
  3. Mixed 350 ul of LB.
  4. Prepared and Labeled two plastic plates with LB plate medium which contained appropriate antibiotics (LBA).
  5. Plated 300 ul of the culture onto first dish and spread.
  6. Mixed 450 ul of LB to 50 ul of the culture and plated 300 ul of it onto second dish and spread.
  7. Incubated the plates at 37C for 19 hrs.
