Gibson of cleaned up PCR products FKBP from 8th September x gblock 2.2 from the 8th September x pSB1C3 treated by DpnI

By Maxence

Gibson was performed with cleaned up PCR products FKBP (insert 1) (obtained the 8th September) x gblock 2.2 (insert 2) (obtained the 8th September) x pSB1C3 treated by DpnI (plasmid) with the following protocol:

For each 20μl of reaction, mix the following reagents :

  • 0.31 µL of insert 1
  • 0.2 µL of insert 2
  • 2 µL of plasmid
  • 7.49 µL of water
  • 10 µL of buffer mix

Two controls were done: one without insert and one without buffer (water was added in order to have a total of 20 µL). The PCR was performed as follow : 1 hour at 50°C.

Transformation of DH5a cells with FKBP - GFP 10 in pSB1C3 (pPS16_018) obtained by Gibson

By Maxence & Mahnaz

Dh5a cells were transformed with pSB1C3 containing FKBP - GFP 10 (pPS16_018), or controls (no buffer mix and plasmid alone) using the usual protocol.



Glycerol stocks of clones X, X, X and X containing FRB - GFP 11 - GFP 1.9 in pSB1C3 (pPS16_022)

"By Maxence, Mahnaz & Coline"

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

  • pPS16_022 (GFP 1.9) clone X
  • pPS16_022 (GFP 1.9) clone X
  • pPS16_022 (GFP 1.9) clone X
  • pPS16_022 (GFP 1.9) clone X

500µL of liquid culture and 250 µL of glycerol 60% were mixed and put at -20°C.

Plasmids extraction of clones X, X, X and X containing FRB - GFP 11 - GFP 1.9 in pSB1C3 (pPS16_022)

"By Maxence, Mahnaz & Coline"

The following plasmids were extracted using the "Charge Switch-Pro Plasmid Miniprep" kit:

  • pPS16_022 (GFP 1.9) clone X
  • pPS16_022 (GFP 1.9) clone X
  • pPS16_022 (GFP 1.9) clone X
  • pPS16_022 (GFP 1.9) clone X

Digestion of plasmids extracted from clones X, X, X and X containing FRB - GFP 11 - GFP 1.9 in pSB1C3 (pPS16_022)

"By Maxence, Mahnaz & Coline"

To assess if DH5a cells were transformed with the good plasmid, plasmid digestion was run with XbaI as following:

  • 1 µL of extracted plasmid
  • 1 µL of buffer
  • 1 µL of restriction enzyme XbaI
  • 7 µL of water

A control was done with 1 µL of non-digested plasmid.

  • pPS16_017 (dCas9 ST - GFP 11) clone X
  • pPS16_017 (dCas9 ST - GFP 11) clone X

500µL of liquid culture and 250 µL of glycerol 60% were mixed and put at -20°C.
