(in Lab: HB, AV, JV)
Objective: To restrict pBAD, sRBS, mRBS, TetR, dT and pTet for the assembly of pBAD-sRBS-TetR-dT-pTet
Method: Used Restriction of Plasmid DNA protocol.
- A front verctor was made made in sRBS ,mRBS, dT plasmids using EcoRI and Xbal enzymes
- pDNA that was cut out of plasmid for a front vector was pBAD, TetR, dT and pLacI using EcoRI and SpeI enzymes
- A back vector was made in sRBS and mRBS plasmids with PstI and SpeI
- pDNA that was cut out of plasmid for a back vector was TeTR and it was restricted with XbaI and PstI
