BAMT PCR Product Eco/Pst Digest

BEGAN AT 11:15 AM

  1. We are cutting the BAMT pcr product (using EcoRI and PstI)--
  2. Total reaction volume is 50μL
  3. the amount of dna desired is about 800 nanograms
    • BAMT pcr product at 58.8 ng/μL -----add 13.6 μL
  4. we are also going to use Dpn1 only in BAMT cut reaction to destroy dna that is not a pcr product (i.e. get rid of extra template)
  1. BAMT pcr cleanup product cut reaction:
    • 28.9 μL water
    • 5 μL NEB buffer 2
    • .5 μL BSA
    • 13.6 μL BAMT pcr cleanup product (concentration = 50 ng/μL)
    • .75 μL Pst1
    • .75 μL EcoR1
    • .5 μL Dpn 1
  2. Incubate tube in 37c room for 1-6 hours, then 20 mins at 80deg C to heat inactivate the enzyme, then 4deg forever.
  3. Did a PCR cleanup & nanodrop: concentration of digested BAMT = ??ng/μL
  4. run a gel before moving on to ligation !!

ATF1 PCR Product Xba/Pst Digest

BEGAN AT 11:15 AM

  1. We are cutting the ATF1 pcr product (using XbaI and PstI)--
  2. Total reaction volume is 50μL
  3. the amount of dna desired is about 800 nanograms
    • ATF1 pcr product at 30.8 ng/μL -----add 26 μL
  4. we are also going to use Dpn1 only in ATF1 cut reaction to destroy dna that is not a pcr product (i.e. get rid of extra template)
  1. ATF1 Digest:
    • 16.5 μL water
    • 5 μL NEB buffer 3
    • .5 μL BSA
    • 26 μL ATF1 pcr cleanup product (concentration = 50 ng/μL)
    • .75 μL Pst1
    • .75 μL XbaI
    • .5 μL Dpn 1
  2. Incubate tube in 37c room for 1-6 hours, then 20 mins at 80deg C to heat inactivate the enzyme, then 4deg forever.
  3. Did a PCR cleanup & nanodrop: concentration of digested SAMT = ??ng/μL
  4. run a gel before moving on to ligation !!

BACKBONE pSB1A3-1 bkb Xba/Pst Digest

BEGAN AT 11:15 AM

    • 35 μL water
    • 5 μL NEB buffer 3
    • .5 μL BSA
    • 8 μL backbone plasmid
    • .75 μL PstI
    • .75 μL XbaI

CONTROL (BSMT-BB) Xba/Pst Digest

    • 31.58 μL water
    • 5 μL NEB buffer 3
    • .5 μL BSA
    • 11.42 μL BSMT-BB (from BSMT miniprep @ 71ng/μL )
    • .75 μL PstI
    • .75 μL XbaI

Glycerols and Miniprep of BSMT biobrick

  1. Did minipreps of A, C, E BSMT liquid cultures to get the BSMT biobrick plasmid.
  2. Made glycerols of these cells (which contain the BSMT biobrick)

SAMT-BB (J45001), BAMT-BB (J45002), & ATF1-BB (J4500x) Ligations

We'll do 5 ligations:

  • EP cut pSB1A3-1 and EP cut SAMT
  • EP cut pSB1A3-1 and EP cut BAMT
  • EP cut pSB1A3-1 and EP cut E0040 (+ Ctrl)
  • XP cut pSB1A3-1 and XP cut ATF1
  • XP cut pSB1A3-1 and XP cut BSMT (+ Ctrl)

General ligation considerations: 10μL total volume, about 50ng of each DNA

BSMT Ligation

  • 1.5μL water
  • 1μL T4 DNA ligase buffer (vortex well before adding, make sure it smells strongly like wet dog!!)
  • .5μL T4 DNA ligase enzyme
  • 5μL cut BSMT (50ng)
  • 2μL cut backbone (50ng)

Control Ligation (Barry's biobrick part)

  • 1.5μL water
  • 1μL T4 DNA ligase buffer (vortex well before adding, make sure it smells strongly like wet dog!!)
  • .5μL T4 DNA ligase enzyme
  • 5μL cut Barry's BB part (50ng)
  • 2μL cut backbone (50ng)

Ligate at room temp for 15 to 20 minutes and then proceed to transformation
