Procedure

Isolation of Mononuclear Cells

  1. o/n grow single colony in 2ml of LB (+ antibiotics)
  2. 1.5 ml into eppendorf.
  3. Pellet cells at max speed in cold room for 1.5 min.
  4. Discard supernatant , leave pellet as dry as possible.
  5. Resuspend pellet in 100 μL Alkaline Lysis SLN1,vortex.
  6. Add 200μL freshly prepared AL2, mix by inverting 5-6 times(DO NOT vortex!)
  7. Put on ice.
  8. Add 300μL AL3,invert tubes to mix.
  9. Incubate on ice for 5 min.
  10. Centrifuge at max speed for 5 min in cold room.
  11. Take the supernatant into a new tube.
  12. Add 900 isopropanol at RT. Vortex
  13. Centrifuge at max speed for 10 min at RT.
  14. Rinse the pellet with 1ml 70%EtOH.
  15. Centrifuge at max speed for 5 min at RT.
  16. Air dry the pellet.
  17. Dissolve each in 50μL TE OR H2O.


Notes

  1. Store solutions at 4 degrees and each time freshly prepare the Buffer 2.
