(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

Objective: Put lumazine synthase gene and mms6 into pET-28(A) for future overexpression.

Method: Restrict mms6 from Mr. Gene with NotI. Large quantities of DNA can be used so a gel extraction of the part can be done. PCR lumazine synthase out of its backbone. Restrict off the extra DNA fragments from the PCR with NotI. Restrict pET-28A with notI. Ligate.
