Secondary Rolony Generation

Samples: Matt:LabNotes/2014-2-21

Procedure

Anneal Padlock Probes

  • 1X Ampligase Buffer
  • 2uM of each padlock probe
  • 0.5 U/ul Ampligase
  • Incubate @ 45C for 24 hours
    • Wrapped in parafilm and put in ziploc with wet towel

200uM ppRAB7A 1
5U/ul Ampligase 10
H2O 77
Total 100
Empty Negative Control (D7 & E7)
  • Not going to waste Ampligase since it's highly unlikely anything will be ligated, but will do RCA in these wells
Pre-circularized Padlock Probes (C7 & C8)
  • Combined all the pre-circle ppMALAT1 made on: Matt:LabNotes/2014-2-10 into 64ul
  • 75% EtOH for 10 minutes
  • Wash with 1X PBS 2 times
  • 0.1N HCl for 2 minutes
  • Wash with 1X PBS 3 times
  • Add 32ul to C7 & C8
Fixed Pre-circularized Padlock Probes (F7 & F8)
  • Not going to do anything during Ampligase step

Secondary RCA

  1. Aspirate each well but don't wash
    • F7 well was dried up
  2. Pre-annealing the FISSEQ_ppRCA primer for the rolling circle amplification reaction.
    1. 3ul of RCA primer(200 uM, GATATCGGGAAGCTGA*A*G) in 597ul of 2xSSC/30% formamide
    2. Preheat primer at 60C (Tm = 55C when not in 30% formamide)
    3. Add 50ul to each well, incubate at 45C for 15min.
    4. Aspirate, and wash using 2x SSC twice
    5. Aspirate, and wash using 0.1x SSC twice
  3. Prepare the rolling circle amplification reaction mixtures on ice.
    1. 513 ul ddH2O,
    2. 60 ul 10x Phi29 buffer,
    3. 6 ul 25 mM dNTP,
    4. 12 ul 2 mM aminoallyl dUTP
    5. 9 ul Phi29 DNA polymerase (Epicentre, low concentration)
      • 600ul Total Volume
  4. Add 50ul to each well and incubate overnight at 30C.
