BA8 Section DARTFISH suppv2 with Fiducial Beads

  • Repeat Matt:LabNotes/2015-8-17 but with fresh PFA and 0.01N HCl (instead of 0.1N during pepsin step) to see if that helps with tissue degradation
  • 3-4 month old BA8 tissue section
  • suppv2 design
  • Use FluoSpheres Amine-Modified Microspheres 0.2um (505/515) as fiducial markers
  • Try only 5min incubation with TX-500 to see if that decreases tissue degradation

DARTFISH on BA8

  1. Prepare plastic culture dish with hole, tweezers, large plastic dish, and 50C hot plate
    • EtOH sterilize and UV
  2. Made 40ml 4% PFA at RT
    • 10ml 16% PFA from ampule + 4ml 10X PBS + 26ml nuclease-free H2O
  3. Take out BA8 section from -80C and incubate on 50C hot plate for 3min
  4. Submerge section in 5ml 4% PFA in 6 well culture plate for 15min at 37C
  5. Wash with 2X SSPE by submerging in 2 clean wells of culture plate with 5ml SSPE
  6. Aspirate any liquid and attach glass to bottom of culture dish with double-sided adhesive
  7. Add 0.25% TX-100 in 2XSSPE and incubate 5min at RT
    • New solution made by Justin
  8. Wash with nuclease-free H2O three times
  9. Add 0.01% Pepsin in 0.1N HCl and incubate for 5min at 37C
    • 2ul 1%Pepsin + 1ul 2N HCl + 197ul H2O
  10. Wash with nuclease-free PBS three times
  11. Prepare Reverse Transcription Mix on ice
