  1. Five thousand cells per well were plated in 96 well plate previously precoated with or without agarose and the drug cytotoxicity was determinate by MTT assay. Each IC50 value is the average of six independent experiments. The symbol (>) indicates that the IC50 was not reached at the highest concentration tested. NS: Not significant.
