Conditioned media (a) and cell lysates (b) from cells grown for 24 h in the absence (0 nM) or presence (100 nM) of concanamycin A were assayed for cathepsin activity. N = 5, error bars ¨C std. dev, Student t test * p < 0.005, ** p < 0.0001. (c) Percent reduction in cathepsin activity following treatment with concanamycin A in conditioned media (CM) and cell lysates (Lysate).
