Linnarsson Protocol

Back to Calendar

I'll be starting work today on the Linnarsson lab protocol for doing RNA FISH on tissue sections. The protocol is given to me from Simone, one of their main RNA FISH researchers, who visited our lab in Dec 2014/Jan 2015.

Buffer Prep

The protocol uses several solutions that are prepared beforehand and aliquoted for later use. Most of these need to only be done once.

  • E Coli tRNA 20 mg/mL
    • tRNA 500 mg
    • RNAse free H2O 12.5 mL
    • aliquot into 500 uL increments and store at -20C
  • DAPI stock solution
    • RNAse free water 250 uL
    • DAPI powder 5 mg
    • aliquot into 20 uL increments and store at -20C
  • DAPI ready to use
    • DAPI stock (20 mg/mL) 10 uL
    • nfH2O 990 uL
    • Store at 4C use within 1 month
  • 70% Ethanol
    • 700mL absolute EtOH
    • 300 mL ddi water
  • Paraformaldehyde 4% w/v
    • Paraformaldehyde 16% w/v 20 mL
    • PBS 10X 8 mL
    • RNAse free H2O 52 mL
    • aliquot into 15 mL increments and store at -20C for up to 4 months
    • thaw the solution with 37C water bath before use
  • Formamide
    • Bring the bottle at RT and prepare 50mL aliquots;
    • store them in the dark at 4C for up to 4 months
    • Work in a fume hood
  • Ribonucleoside Vanadyl complex (200mM)
    • Incubate the purchased solution in a water bath at 65C for 10 minutes
    • Aliquot in 100 uL and store up to 4 months at -20C
  • BSA 50 mg/mL
    • BSA 500 mg
    • RNAse free water 10 mL
    • Aliquot in 500 uL and store at -20C up to 4 months
