RCA + Circularization Test[edit]

Back to Calendar

Repeating the circularization and RCA test using the three different polymerase enzymes to classify which is best to use. This will use the C4-C2 template, which is the simplified template that is the equivalent of the two C probe arms ligated and gap-filled.

Protocol-Part 1[edit]

Sample Matrix

Sample Condition
Sample 1 (ABC) Sample
Sample 2 (ABC) No Padlock PO4
  1. Phosphorylation-Padlock0501
    1. Set up reaction according to table

    3. Incubate at 37C for 30 min
    4. Heat kill enzyme with 15 minutes at 65C
  2. Template-Bead Binding
    1. Suspend 2 uL (8 ug) beads per sample in 100 uL wash buffer
    2. Apply magnet for 30 sec and remove supernatant
    3. Dilute 5 uL C4-C2 template into 45 uL nfH2O
    4. Add 2 uL diluted template per sample to bead solution; incubate at RT for 5 min
    5. Wash beads with 100 uL wash buffer; vortex to suspend; apply magnet and remove supernatant
  3. Padlock Hybridization
    1. Make following 6.1X master mixes
    2. Reagent MM1 (uL) MM2 (uL)
      Padlock0501 0 3.1
      PNK Reaction 6.2 0

      Total 62 62
    3. Resuspend sample in 20 uL padlock buffer
    4. Incubate at 37C for 30 minutes
    5. Wash twice with wash buffer

Protocol-Part 2[edit]

  1. Circularization
    1. Prepare 6.5X uL Phusion mix
    2. Reagent Stock Conc Final Amount 1x Vol (uL) MM Vol (6.5x) (uL)

      nf H2O     1.2 7.8
      Total     20 130
    3. Add 20 uL phusion mix to 20 uL reaction
    4. Incubate at 55C for 2 hours
  2. Exonuclease Digestion
    1. Mix 12.5 uL Exo I (20U/uL) and 2.5 uL ExoIII (100U/uL)
    2. Add 2 uL to each sample, mix by swirling pipette tip
    3. Incubate for 1 hour at 37C
    4. Heat kill by incubating for 5 min at 95C
