Immunize then harvest the draining lymph nodes.  The draining lymph nodes
can be used as is -- they contain T cells and accessory cells needed
for antigen presentation.  You can choose to purify the T cells.
If you do so you will need to add accessory cells back into the
culture.  The most common way to do this is to use irradiated spleen
cells (they must be irradiated to stop them from proliferating and
giving high background scores).  By far the easiest way to do the
experiment is to use the lymph node cells without additional purification.
