Fig. 1From: Sialylation of chitosan to mitigate Aβ toxicityGating layout of FCMS apoptosis assay. The cells fall into one of four categories from the apoptosis assay. These categories are: Alive (Q1 – low 7-AAD and low Annexin V PE), Early apoptotic (Q2 – low 7-AAD and high Annexin V PE), Late apoptotic (Q3 – high 7-AAD and high Annexin V PE), and Necrotic (Q4 – high 7-AAD and low Annexin V PE)Back to article page
