the only other thing besides trypsin i could think of is to use a
magnetically labelled secondary antibody. dependent on cell type, the
resulting capping will fall off. cells would be incubated with antibody and
cultured overnight at 37C upright in a flask or tube with an attached magnet
(i.e. 15ml snap cap and a dynal MPC-1). though this is probably more trouble
than its worth.
