Program

  • 95C 30sec -> cool down to 55 C at 0.02C/sec -> 55 C 16h
    • Should have added RiboLock after reached 55C since it would be denatured at 95C
  • Ampligase: add 3ul AmpLigase enzyme mix (0.5U/ul AmpLigase in 1X AmpLigase buffer)
  • SplintR: add 3ul SplintR enzyme mix (10ul SplintR + 2ul 10X SplintR Buffer + 4ul Ribolock + 4ul H2O)
  • Ampligase: -> 55 C 20h -> 94C 2min -> add 2ul Exo I/III mix -> 37C 1h -> 94C 2min -> 4C hold
  • SplintR: -> 37 C 30min -> 94C 10min -> add 2ul Exo I/III mix -> 37C 1h -> 94C 2 min -> 4C hold
  • Take 30ul and purify with Zymo columns
    • Left in 4C 1 hour after first column spin down
    • Elute 10ul

  • No separation between DNA, RNA, and NTC samples for SplintR
  • Sequence results to see if there's no difference really
    • Stop Ampligase NTC at 28 cycles
    • Stop others at 19 cycles

Excel data with PCR curve File:2017-07-10 Agi15kFeb17V4 invitroCapture SeqLibrarySizeCheck.jpg

  • Only Ampligase NTC band looks different, otherwise every sample has bands of expected size for captured padlock probes with sequencing adapters
  • Nanodrop: every sample was ~500ng/ul +/- 10ng/ul
  • Mix Samples 1&2, 3&4&5, 6&7&8 in equal ratios (20ul each)
  • Gel size selection 3 lanes
    • Load each well with 10ul mix (~5ug) + 10ul 6x loading buffer

  • Cut out band and shear through 0.5ul tube into 2.0ul tube
  • Add 450ul 1X TE Buffer and vortexed at 37C for 1hr
  • Centrifuged at 15,000 rpm for 3 min at RT
  • Transferred the clear spnt. to Nanosep columns and centrifuged at 15,000 rpm for 3 min
  • Transferred the lower layer to Nanosep again and centrifuged at 15,000 rpm for 3 min
  • Transferred spnt to fresh 1.5 mL tube
  • Precipitated in 3 1.5ml tubes with 1000ul of 100% EtOH, 1.4ul of Glycoblue, 44ul of 3M NaoAc pH 5.2

  • Spun 8 tubes at 10,000rpm at 4C for 30min
  • Discard supernatant and add 650ul cold 80% EtOH and spin at 14,000rpm at 4C for 5min
  • Discard supernatant and let dry in hood for 10min
  • Resuspend each tube with 10ul and combine
