Flow cytometric analysis of treated/untreated HT-29 cancerous cells. Cells were treated with FITC-Annexin V in combination with PI to detect apoptosis and necrosis before being subjected for analysis by flow cytometry. Dots with Annexin V−/PI+ (Q1), Annexin V+/PI+ (Q2), Annexin V+/PI− (Q3), and Annexin V−/PI− (Q4) and feature represent necrotic, late apoptotic, early apoptotic, and viable intact cells, respectively. a Control; b 5-FU; c B. adolescentis; d B. animalis subsp. lactis; e B. animalis subsp. animalis; f B. bifidum; g B.‌ angulatum
