Use | Calculin A is A potent, cell-permeable inhibitor of protein phosphatase 1 (PP1) and protein phosphatase 2A (PP2A) with IC50 values of 2 nM and 0.5-1 nM, respectively. |
In vitro study | Calyculin A (1-10 nM; 24 hours) induces cytotoxicity in MG63 cells in a dose-dependent manner up to 10 nM in MG63 cells. Cell Cytotoxicity Assay Cell Line: Human osteosarcoma MG63 cells Concentration: 0, 1, 2, 5, 10 nM Incubation Time: 24 hours Result: Treatment with 0.1 nM for 24 h had a minimal effect on MG63 cell survival. Cell rounding and shrinking were obvious in the cultures treated for 24 h with 5 nM. The level of the cell viability treated with 10 nM was 27% that of the control cultures. |
