Tandab bind to the CD20-positive SU-DHL-2/4 cells. A The fluorescence image of Tandab bound to SU-DHL-2 and SU-DHL-4 cells. Green and red represent CD20 and 6 × His Tag, respectively. B Flow cytometric analysis of Tandab bound to SU-DHL-2/4 cells. Blue: negative control, red: experimental groups treated with UCMSCs-Tandab(IL-6/CD20). C The competitive binding assay with anti-human CD20 monoclonal antibody. Blue: negative control, red: Tandab(IL-6/CD20) + anti-human CD20 monoclonal antibody, orange: anti-human CD20 monoclonal antibody alone
