Additional Reagents (Not Supplied):
NOTE: To properly analyze the data, the following control target cell groups are needed to set up the flow cytometer and compensation:
|Effector:Target Ratio||Effector Cell Suspension||Target Cell Suspension||Target Cell Medium||Final Volume|
|0||0 ml||1.5 ml||0 ml||1.5 ml|
|6.25:1||0.125 ml||1 ml||0.375 ml||1.5 ml|
|12.5:1||0.25 ml||1 ml||0.25 ml||1.5 ml|
|25:1||0.5 ml||1 ml||0 ml||1.5 ml|
NOTE: If additional surface markers are to be assayed, staining can be inserted at this point in the protocol.
