Yep this is a good way of doing it before then pulling down with something
like dynal beads.

Remember always to then do  an Ab check for markers on sparse clones


One thing not to do is grow the culture to confluence as epithellial and
endothellial will excise thmselves as rounded cells in the middle of a
clone and come out with the lymph's in Lesley's method
