Version 2 Oligos[edit]

Back to Calendar

The version 2 oligos have several changes. The main is that they are shorter and use a UMI on the padlock instead of the latch. I will test these oligos and the new protocol. I'm also going to check

Sample Matrix[edit]

Sample Condition
Sample 1 (AB) Normal
Sample 2 (AB) No Template
Sample 3 (AB) No C probes
Sample 4 (AB) No phosphate activation

Protocol-Phase 1[edit]

  1. Phosphorylation-MirrorC Probe B (PCCB-02)

      Total     20
    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. Add 2 uL 10 uM template oligo per sample to bead solution; incubate at RT for 5 min
    4. Wash beads with 100 uL wash buffer; vortex to suspend; apply magnet and remove supernatant
  3. C Probe Hybridization
    1. Combine following into a 0.2 mL tube
    2. Reagent uL per Sample uL Total
      PCCA 1 8
      Mirror C Probe B reaction 2 16
      Wash buffer 2 16
      Total 5 40
    3. Heat C probes to 90C for 5 min; Chill probes on ice to quench
    4. Add 5 uL probe mixture to beads
    5. Incubate at 40C for 1 hour with agitation; start part 4 after incubation begins
    6. Wash beads with 100 uL wash buffer; apply magnet and remove supernatant
    7. Repeat wash step above
    8. Add 100 uL cold Low Salt Buffer; apply magnet and remove supernatant
