Treatment with Stachydrine hydrochloride (50µM, 200µM, 500µM and 1000µM) noticeably inhibited MCF-7 and T47D cell proliferation in dose- and time-dependent manner. High concentrations (500µM and 1000µM) of Stachydrine significantly increased the frequency of both studied cell lines at the G1 phase of cell cycle, suggesting that Stachydrine hydrochloride could cause cell cycle arrest   推荐实验方法(仅供参考) Cell Assay Cell Proliferation Assay Cell Cycle Analysis MCF-7 and T47D cells 50µM, 200µM, 500µM and 1000µM 24 and 48 hours CCK-8 cell counting assay is used to detect proliferation of MCF-7 and T47D cells when treated with Stachydrine hydrochloride at four different concentrations (50µM, 200µM, 500µM and 1000µM) for 24 and 48 hours. Cell cycle analysis of MCF-7 and T47D cells is determined by flow cytometry. Experiments are performed in triplicates and representative images are presented.
