+ | ''By Mahnaz'' | ||
+ | |||
+ | Fragment 1.1 and 1.2 were ligated together as following to create fragment 1 | ||
+ | * 4µL of Fragment 1.1 PCR product from the 02/09/2016 | ||
+ | * 4µM of Fragment 1.2 PCR product from 02/09/2016 | ||
+ | * 1µL of Buffer T4 10X | ||
+ | * 1µL of ligase T4 enzyme | ||
+ | |||
+ | Fragment 2.1 and 2.2 were ligated together as following to create fragment 2 | ||
+ | * 4µL of Fragment 2.1 PCR product from the 02/09/2016 | ||
+ | * 4µM of Fragment 2.2 PCR product from 02/09/2016 | ||
+ | * 1µL of Buffer T4 10X | ||
+ | * 1µL of ligase T4 enzyme | ||
+ | |||
+ | The ligation product was put at room temperature for 1 hour. | ||
+ | |||
+ | ==== Clean-up of ligation products ==== | ||
+ | ''By Mahnaz'' | ||
+ | |||
+ | Ligation product (fragement 1 and fragment 2) obtained were cleaned up by using the NucleoSpin Gel and PCR Clean-up kit [[Team:Paris_Saclay/Experiments#Purification|protocol]]. | ||
+ | |||
+ | ====Q5 PCR and phusion PCR on ligation product ==== | ||
+ | ''By Mahnaz'' | ||
+ | |||
+ | Q5 and phusion PCR was performed on the ligation product (fragment 1 and fragment 2) with the following protocol: | ||
+ | For each 50μl of reaction, mix the following reagents: | ||
+ | * 1 µL of plasmid | ||
+ | * 1 µL of dNTPs (10mM) | ||
+ | * 1 µL of each primer mix (10µM) | ||
+ | * 10 µL of Q5 buffer (5X) | ||
+ | * 0,5 µL of Q5 high fidelity polymerase | ||
+ | * 35,5 µL of nuclease free water | ||
+ | |||
+ | Mix gently and aliquot 50 μl of the mix into the PCR tubes on ice. | ||
+ | Perform PCR as follow: | ||

+ | ====Gibson of cleaned up PCR products fragment 1 and fragment 2 in pSB1C3 treated by DpnI==== | ||
+ | ''By Manhaz '' | ||
+ | |||
+ | Gibson was performed with cleaned up PCR products fragment1 x fragment 2 x pSB1C3 treated by DpnI (plasmid) with the following protocol: | ||
+ | |||
+ | For each 20μl of reaction, mix the following reagents : | ||
+ | |||
+ | * the 1-2 Gibson assembly product tube : 1,12µL of purified segment 1 and 0,56µL of purified segment 2 + 0,85µL of digested pSB1C3 + 7,47 µL of sterile water + 10µL of NEB Builder Hifi DNA Assembler Master Mix | ||
+ | * the control tube : 0,85µL of digested pSB1C3 + 17,47 µL of sterile water | ||
+ | |||
+ | Gibson products were incubated 1h at 52°c. | ||
