In our lab we often need to make T cell rich populations, specifically CD4+
and CD8+, and we use the MACS system. It gives great yields. They use an
anti-CD4 or anti-CD8 Ab conjugated to a metallic bead. This solution is
then passed through a column with steel shavings in it. The column sits in
a huge magnet, and your desired fraction is either eluted out, or remains in
the column. It is a bit slow, and VERY costly. I hope this helps.
