Summary

Although trypsin-disaggregated embryonic chick neural retina cells are incapable while EDTA-disaggregated cells are capable of immediate aggregation in culture, cells from both populations exhibit equally negligible levels of cell surface proteolytic activity as measured by substrate assay. The trypsin-induced lag does not appear, therefore, to depend upon adsorbed enzyme.
