Our bioassay
Alomone Labs Calyculin A inhibits the growth of breast cancer epithelial MCF7 cells.Cells were incubated with different concentrations of Calyculin A (#C-100) for four days. Cell number was measured using the methylene blue method. The number of cells was normalized with respect to the control (100%) and plotted against Calyculin A concentrations.
Scientific background Calyculin A was initially isolated from the marine sponge Discodermia calyx.1 It is a very potent, cell-permeable PP-1 and PP-2 inhibitor (IC50 2nM and 0.5-1nM respectively),2 and extremely specific for PP-1 and PP-2A among other acidic, alkaline and protein phosphatases.2,3
