August 3/2010

(In Lab: HB)

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

• For all reactions
  • 158 (µL) Milli-Q H₂O
  • 10 (µL) Buffer
  • 0.5(µL) of each enzyme
  • 10 (µL) pDNA

Restriction was incubated for 1 hour at 37⁰C

(In Lab:K.G J.S)

Objective: To run 1.5% agarose of restrictions: pBAD, sRBS, mRBS, TetR, dT and pTet for the assembly of pBAD-sRBS-TetR-dT-pTet

Method: Used a 1.5% agarose gel with 2 (µL) of loading dye and 10 (µL) of pDNA.

all ligations were transformed

Objective: Transform

Method: used Competent Cell Transformation protocol

• changes:
  • used 50µL aliquottes of DH5&alpha
  • did not pipette up and down once, the cells were just swirled 3 times
  • added 400µL SOC media, shoock at 37⁰C for 90 min
  • platted 250µL and 150µL
    

Incubated from 12:00AM to 4;00 PM
