In | + | Plasmids pPS16_005 and pPS16_006 containing gBlocks 3.1 and 3.2 were sent to sequencing. Sequencing revealed that clones 1 transformed with pPS16_005 and clone 4 transformed with pPS16_006 had the good insert in their plasmid. In order to assembled both inserts, a PCR with Q5® High-Fidelity 2X Master Mix was performed on these clones following [[Team:Paris_Saclay/Experiments#Q5PCR|this protocol]]. [[Team:Paris_Saclay/Experiments#primers|iPS83 and iPS126]] primers were used. Annealing temperature was 72°C. After amplification, 1 µL of loading dye was added to 5µL of each PCR products. Then 5 µL of this mix were put on gel. PCR products were migrated 25min at 100V. |

[[Team:Paris_Saclay/Experiments#primers|Specific primers]] were used to amplify. These primers will allow Gibson assembly afterward : Ptet_R and Ptet_F for the plasmids, Link-TDdcas_F and Ter_TDdcas_R for DS_TDcasN, Tet-SPdcas_F and Link-SPdcas_R for DS-SPcasN-. |
