To try and help you on the topic here is a small GIF with first plot showing
CD45RA-FITC and CD45RO-PE stained human lymphocytes previously gated on
CD4-PECy5 positive and scatter gate. These are sorting regions around
populations and on the right are plots showing sorted cells. Although there
is a spread of cells (++?) between 2 populations, these gates were
"selective" enough to include single positive cells only. When doing
analysis one could be even more generous in setting these gates.
