Rituximab-monomethyl auristatin E (MMAE) induced apoptosis in non-Hodgkin lymphoma cells. Apoptosis induced by Rituximab-MMAE was detected by western blot and flow cytometry (FCM). Ramos and Daudi cells were incubated in different concentration of Rituximab-MMAE. (A,B) Apoptosis was detected by FCM. The percentage of Annexin V+ PI− and Annexin V+ PI+ cells (apoptosis cells) was shown in right bar chart. (C,D) The protein level of poly ADP-ribose polymerase (PARP), cleaved PARP, cleaved caspase 9, cleaved caspase 3, Bax, and Bcl-2 was detected by western blot; β-actin was used as a loading control. Densitometric values were quantified by Image J software.
