Positive Control Amplicon Production (PCAmp4)

Back to Calendar

Protocol

  1. Phosphorylation
    1. In a 0.2 mL tube, add ingredients according to table
    2. Reagent Stock Conc Final Conc./Amount uL added
      AmpLigase Reaction Buffer 10X 1X 2
      ATP 10 mM 1 mM 2
      PCAmp2 100 uM 1 nmol total 10
      T4 DNA Kinase 10 U/uL 10 U 1
      nfH2O NA NA 5
      Total     20
    3. Incubate at 37C for 30 min
  2. Ligation
    1. Set up 2 reactions with the following reagents (DO NOT ADD LIGASE YET)
    2. Reagent Stock Conc Final Conc./Amount uL added
      AmpLigase Reaction Buffer 10X 1X 4
      Latch Oligo 100 uM 500 umol 5
      5' Amplicon Oligo 100 uM 500 umol 5
      Amp Ligase 5 U/uL 5 U 1
      Phosphate Reaction NA NA 10
      nfH2O NA NA 25
      Total     50
    3. Add amplicons according to following table
    4. Sample PCAmp1 PCAmp3 LatchX2 LatchX3
      AmpliconX1 X   X  
      AmpliconX3   X   X
    5. Heat reaction to 95C for 5 min
    6. Lower temp to 55C
    7. Add 1 uL Amp Ligase to each reaction without removing from thermocycler; swirl with pipette tip 5 times to mix
    8. Incubate at 55C for 2 hours
    9. Heat to 95 C to denature dsDNA
    10. Purify with ssDNA column
  3. ssDNA Column
    1. Add 100 uL Binding Buffer to the sample; mix well
    2. Transfer to IIC Column and centrifuge at 14000 rpm for 1 minute; SAVE THE FLOW THROUGH
    3. Add 150 uL 100% EtOH to flow through; mix well
    4. Transfer to IC Column and centrifuge at 14000 rpm for 1 minute; discard flow through
    5. Add 400 uL Prep Buffer and centrifuge at 14000 rpm for 1 minute; discard flow through
    6. Add 700 uL Wash Buffer and centrifuge at 14000 rpm for 1 minute; discard flow through
    7. Add 400 uL Wash Buffer and centrifuge at 14000 rpm for 1 minute; discard flow through
    8. Centrifuge empty column at 14000 rpm for 2 minutes
    9. Transfer to empty 1.5mL centrifuge tube (low bind)
    10. Add 30 uL nfH2O and centrifuge at 14000 rpm for 1 minute
