Plasmids extraction of FRB - GFP 11 in pSB1C3 (pPS16_019) clone 4 and FKBP - GFP 10 in pSB1C3 (pPS16_018) clone 6

"By Maxence & Yacine"

The following plasmids were extracted using a "standard Plasmid Miniprep" kit:

  • pPS16_018 (FKBP - GFP 10) clone 6
  • pPS16_019 (FRB - GFP 11) clone 4

Cloning of FRB - GFP 11 (pPS16_019) in FKBP - GFP 10 - pSB1C3 (pPS16_018) by digestion-ligation

By Maxence & Yacine

For that purpose, FRB - GFP 11 (pPS16_019) clone 4 was cut by restriction enzymes XbaI & PstI as following:

  • 20 µL of FRB - GFP 11 (pPS16_019) clone 4
  • 4 µL of buffer FD
  • 2 µL of restriction enzyme XbaI
  • 2 µL of restriction enzyme PstI
  • 10 µL of water

And FKBP - GFP 10 - pSB1C3 (pPS16_018) clone 6 was cut by restriction enzymes PstI & XbaI and was treated by the alkaline phosphatase FastAP (dephosphorylation of cloning vector DNA to prevent recircularization during ligation) as following:


  • 20 µL of FKBP - GFP 10 - pSB1C3 (pPS16_018) clone 6
  • 4 µL of buffer FD
  • 2 µL of restriction enzyme SpeI
  • 2 µL of restriction enzyme PstI
  • 2 µL of alkaline phosphatase FastAP
  • 10 µL of water

The mix were incubated for 20 minutes at 37°C. Then, 40 µL of each digestion products and 5 µL of DNA ladder were placed in wells and migrated at 100V during 30 min.

Migration products expected were :

Migration products Expected band size (bp)
Template digested (pPS16_019 treated by XbaI & PstI) 727
Vector digested (pPS16_018 treated by SpeI & PstI) 2784

GEL

The digestion products were cleaned up from the gel by using the NucleoSpin Gel and PCR Clean-up kit protocol.
