Real Time qPCR

Materials

  • cDNA for templates
  • Qiashredder and RNEasy kits from Qiagen
  • Superscript Kit from Invitrogen
  • SyberGreen PCR Master Mix Applied Biosystems
  • 96 well qPCR plate
  • Primers (Dilute to 5 uM mixture of fwd and rev and then make a working solution of 0.4 uL + 4.6 uL water per reaction)
  • Generate primers using http://pga.mgh.harvard.edu/primerbank/index.html

Protocol

RNA Extraction

  1. Use RNEasy kit with Qiashredder. see Harvesting RNA from Cells grown in monolayer. For a 12 well plate, use 350 uL of RLT (add 10 uL B-ME per 1 mL of RLT buffer).
  2. Scrape cells and pass through Qiashredder column. Do the optional DNAse step at step 5 using the RNAse free DNAse from Qiagen.
  3. Store at -20 until RT reaction

RT-PCR Reaction

  1. Use 8 uL of RNA per RT reaction.
  2. Use Superscript RT-PCR kit from Invitrogen, following manufacturers instructions
  3. Store cDNA at -20 until use
  4. Typically dilute 5X in water (adjust for higher or lower expressing transcripts)

Plate Preparation

  1. Book 3h on qPCR machine at http://felix2.lsi.umich.edu/ORS
  2. Prepare primer mix from 5 uM primer pair stocks. Per reaction add 0.4 uL primers + 4.6 uL water.
  3. Get 96 well block and keep on rack. Do not touch bottom of plate.
  4. Add 5 uL template per well.
  5. Add 5 uL primer per well.
  6. Add 10 uL per row into 8 wells of a PCR strip plus an extra 10-20 uL
  7. Using a multichannel pipettor, add 10 uL Master mix to each well
  8. Start qPCR Machine using the machine in the Lin Lab or the Saltiel Lab machine
