Example 9
After treating BT474 cells with different concentrations of HS-106 for 24 hours, the annexin V assay was executed as previously described (Safi et al., 2014). Briefly, cells were collected and stained with Alexa Fluor 488 Annexin V and Sytox Red according to the manufacturer's protocol. Annexin V-positive cells were considered apoptotic, and their percentage of the total number of cells was calculated. Ten thousand events were collected for each sample using a BD Accuri C6 flow cytometer (BD), and data were analyzed using the CFlow Plus program software (BD) and FCS express (De Novo Software).
