Visualization

PCR of GFP 1.9 in pUC19 (pPS16_009) and GFP 1.9 in gblock

By Sylvie

A new PCR was run in order to obtain a new GFP 1.9 PCR product. For each amplification, two matrix were used: GFP 1.9 in pUC19 (pPS16_009) and GFP 1.9 in gblock.

For each 50μl of reaction, mix the following reagents :

  • 1 µL of matrix (diluted 10X)
  • 1 µL of dNTPs (10mM)
  • 2.5 µL of each primer mix (10µM)
  • 10 µL of buffer (5X)
  • 0,5 µL of Phusion polymerase
  • 30 µL of nuclease free water
  • 1.5 µL of DMSO

Mix gently and aliquot 50 μl of the mix into the PCR tubes on ice. Perform PCR as follow:

Step Temperature Time
Initial denaturation 98°C 30sec
30 cycles 98°C 10sec
60°C 30sec
72°C 30 sec
Final Extension 72°C 5min
Hold 4°C $\infty$

Primers used were:

Matrix GFP 1.9 in pUC19 (pPS16_009) or GFP 1.9 in gblock
Primers iPS84 and iPS140

PCR of 24 extracted GFP 1.9 in pSB1C3 (pPS16_020) from the 13th October

By Sylvie

A PCR was run on 24 extracted plasmids pPS16_020 in order to verify if the clonage worked.

For each 50μl of reaction, mix the following reagents :

  • 1 µL of matrix
  • 1 µL of dNTPs (10mM)
  • 2.5 µL of each primer mix (10µM)
  • 10 µL of buffer (5X)
  • 0,5 µL of Phusion polymerase
  • 31.5 µL of nuclease free water

Mix gently and aliquot 50 μl of the mix into the PCR tubes on ice. Perform PCR as follow:

Step Temperature Time
Initial denaturation 95°C 5min
30 cycles 95°C 30sec
48°C 30sec
72°C 30 sec
Final Extension 72°C 5min
Hold 4°C $\infty$

Primers used were:

Matrix GFP 1.9 in pSB1C3 (pPS16_020) extracted the 13th October
Primers iPS168 and iPS169

Gel of PCR products

By Sylvie

5 µL of PCR products and 20 µL of DNA ladder were placed in wells and migrated at 100V during 30 min, in odrder to verify the DNA quantity.

PCR products expected were :

PCR products Expected band size (bp)
GFP 1.9 (iPS84 & iPS140) 862
GFP 1.9 (iPS168 & iPS169) 1135

GEL SYLVIE 7

No good clones were obtained for GFP 1.9 in pSB1C3 (pPS16_020).

Digestion of FRB - GFP 11 - FKBP - GFP 10 in pSB1C3 (pPS16_021), GFP 1.9 PCR product and linearized pSB1C3

Linearized pSB1C3 was digested by restriction enzymes XbaI & PstI:

  • 4 µL of plasmid
  • 1 µL of buffer FD
  • 0.5 µL of restriction enzyme XbaI
  • 0.5 µL of restriction enzyme PstI
  • 2 µL of water

GFP 1.9 PCR product was digested by restriction enzymes XbaI & PstI:

  • 5 µL of GFP 1.9 PCR product
  • 1.5 µL of buffer FD
  • 1 µL of restriction enzyme XbaI
  • 1 µL of restriction enzyme PstI
  • 6.5 µL of water

FRB - GFP 11 - FKBP - GFP 10 in pSB1C3 (pPS16_021) was digested by restriction enzymes SpeI & PstI:

  • 10 µL plasmid
  • 2 µL of buffer FD
  • 1 µL of restriction enzyme SpeI
  • 1 µL of restriction enzyme PstI
  • 6 µL of water

The mix were incubated for 30 minutes at 37°C.

Ligation of GFP 1.9 PCR product with PCR blunt

DNA ligase was used to join the sticky ends of the template and vector together:

  • 1 µL of vector
  • 3 µL of GFP 1.9 PCR product
  • 2 µL of Buffer T4 10X
  • 1 µL of ligase T4 enzyme
  • 3 µL of water

The mix were incubated for 30 minutes at rooming temperature.

Co-transformation of DH5a cells with FRB - GFP 11 - FKBP - GFP 10 in pSB1C3 (pPS16_021) and GFP 1.9 in pUC19 (pPS16_009)

By Sylvie

Dh5a cells were co-transformed with pSB1C3 containing FRB - GFP 11 - FKBP - GFP 10 (pPS16_021) and with pUC19 containing GFP 1.9 (pPS16_009) using the usual protocol. For that purpose, petri dishes used contained LB + Amp + Cm and two concentration of plasmids were used: 1 µL of plasmids not diluted and 1 µL of plasmids diluted 10X.

Glycerol stocks of clones containing FRB - GFP 11 - FKBP - GFP 10 in pSB1C3 (pPS16_021)

By Sylvie

The glycerol stock of the bacteria with the following plasmids were made.

  • pPS16_021 (FRB - GFP 11 - FKBP - GFP 10)
