Figure 2. In vitro characterization on RAMOS cells.
(a) Flow cytometric evaluation of CD38 expression by RAMOS, detected with IL2-αCD38-αCD38-scTRAIL. (b) Microscopic fluorescence analysis of CD38 expression on RAMOS tumor section detected with αCD38 (SIP) (green for anti-human IgE, AlexaFluor 488) and anti CD31 (red, AlexaFluor 594), 20x magnification, scale bar = 100μm. (c) TRAIL bioactivity assay, based on the killing of RAMOS cell.
