Human NK cells are characterized as CD3 - CD56 + cells. Different subtypes can be distinguished according to the expression level of CD56 and CD16. NKp46, NKp30, CD57, CD94, Perforin, Granzym B and NKG2D are markers that can correlate with the effector function of the NK-cells

5 Created by judith.eckl Page 5 of 8 09/06/2011 Protocoll FACS-staining Reagent set-up: 1. Before starting with the experiment make sure that you have read and understood the whole protocol and that all necessary materials are available 2. Dye preparation Live/Dead Fixable Dead Cell Stain Kit. Bring one vial of the fluorescent reactive dye (Component A) and the vial of anhydrous 3. DMSO (Component B) to room temperature before removing the caps.. Add 50 μl of DMSO (compound B) to the vial of reactive dye (compound A). Mix well and visually confirm that all of the dye has dissolved. One vial can be used for 80 stainings. The remaining Live/Dead Fixable -solution is stable for 8 weeks at -20 C. 4. Preparation of Fixation/Permeabilisation working solution: 1 Part Fixation/Permeabilisation Concentrate is mixed with 3 parts Fixation/Permeabilisation Diluent of the Foxp3 Staining Buffer Set. Per well of a 96well Plate 250µl of working solution has to be prepared. Buffer has to be prepared freshly on the day of experiment! 5. Preparation of the Permeabilisation buffer: The 10x Permeabilisation buffer is diluted with aqua bidest to 1x concentration 6. Preparation of FACS-Buffer: 200ml PBS w/o Mg&Ca 2%BSA, 2mM EDTA and 0,002% NaN 3 are mixed 7. The staining is performed in a 96roundbottom plate. The plate is signed with the date of the experiment and the name of the person performing the experiment. Make sure to cover the plate during all incubation phases and centrifugation steps to minimize contaminations. Make sure that a pellet is visible after centrifugation. 8. To minimize the risk mixing up the samples note all samples and their location on the plate layout on page To wash the wells the washing solution is filled into a clean reagent reservoir and the solution is pipetted with a multichannel pipette into the wells. The cells are washed with careful up and down pipetting. Air bubbles should be avoided as much as possible.

8 Created by judith.eckl Page 8 of 8 09/06/2011 Antibody-staining: 1. 1*10 6 cells per well are given into the 96well plate according to the plate layout (page 5). Don t forget the FMO Control! 2. centrifugation 1600rpm 6 Minutes 4 C 3. Discard the supernatant. Avoid cross contamination and blot the plate on a clean tissue. 4. Per sample 0, 5µl Live/Dead Fixable Solution is mixed with 100µl PBS. This is sufficient for 0, 5*10 5 to 1*10 6 Cells. Always prepare for 2 samples more than necessary. 5. Loosen the pellet with gentle vortexing and resuspend the cells in the 100µl Fixable blue/pbs solution as prepared in step 4 and mix well. Prepare the live/dead compensation beads according to the instructions on page Incubate the cells for 30 Minutes at 4 C in the Dark. 7. In the meantime prepare an antibody working solution containing all surface antibodies, label the tube and spin down the solution. Always prepare for 2 samples more than necessary. 8. Wash the cells with 200µl PBS, 9. centrifugation 1600rpm 6 Minutes 4 C, discard the supernatant 10. Loosen the pellet with gentle vortexing and resuspend the cells in 50µl FACS buffer and add the appropriate amount of surface antibody working solution. Mix well! 11.

Prepare the antibody compensation beads according to the instructions on page Wash the cells with 200µl FACS-Buffer 13. centrifugation 1600rpm 6 Minutes 4 C, discard the supernatant 14. Loosen the pellet with gentle vortexing and at 200µl of the freshly prepared Fixation/Permeabilisation working solution to all samples and mix well 15. Incubate for 30 Minutes at 4 C in the Dark. 16. centrifugation 1800rpm 6 Minutes 4 C, discard the supernatant 17. wash the cells with 200µl Permeabilisation Buffer, 18. centrifugation 1800rpm 6 Minutes 4 C, discard the supernatant 19.

Optional: Resuspend cells in 100µl 1%PFA in PBS and store sealed plate in the fridge overnight, if cells can not be measured the same day. 25. Measure and acquire the data at the Flow cytometer (e.g. LSR II, ). Be aware that permeabilized cells are smaller as the non-permeabilzed cells and adjust the FSC/SSC settings accordingly.
