MagBead Cleanup:

  • Equilibrate Beads to room Temperature

  • Add 15uL of ultra pure water to each well.

  • Add 24 ul of MagBeads to each well.

  • Pipette mix up and down 10 times.

  • Incubate at RT for 5 minutes

  • Secure plate on magnet plate; incubate at RT for 5 minutes (until wells are clear)

  • Remove 65 ul from each well; keep tips to left or right depending on the column to avoid bead pellet.

  • Add 100 ul Fresh 80% EtOH to each well. Incubate 30 seconds. Remove 100 ul from each well

  • Add 100 ul Fresh 80% EtOH to each well. Incubate 30 seconds. Remove 100 ul from each well

  • Reaspirate from each well to assure maximum EtOH removal

  • Allow plate to air dry for 7 minutes.

  • Remove sample plate from magnet plate.

  • Add 40 ul TE; pipette mix 10+ times. Incubate 2 minutes at RT.

  • Place sample plate back on magnet for 5 minutes or until all wells are cleared.

  • Transfer 40 ul to labeled transparent plate (Plate name_PCR_MIDs)

qPCR

  • Make 1:1000 dilutions of wells B3 & H6 from the PCR plate by adding 1 ul to 999 ul TE in a deep well plate:
