Screening for inducer of K-562 cell differentiation.

Outlines:

K-562 cells were cultured in RPMI 11640 medium containing 10% FCS. Two hundred ul of the cells (5 x 104 cells/ml) were put into each well of a 96 well plate, and various concentrations of test compounds were added to the cells, which were incubated for 96 hours at 37 oC in a 5 % CO2 incubator. The morphological change of the cells was observed under a microscope. The inducing activity on K-562 cell differentiation was estimated by benzidine staining.

Compounds:Respinomycinse
