Figure 5From: Cloning and characterization of an adenoviral vector for highly efficient and doxycycline – suppressible expression of bioactive human single – chain interleukin 12 in colon cancerFACS analysis. FACS analysis of IFN-γ in CD3-gated MNC after preactivation by anti-CD3 and CD28 (negative control), additional stimulation with standardized heterodimeric human IL-12 (WHO IL12-standard) and adenovirally produced single-chain IL-12 (p40.linker.p35). A: comparison of representative samples, B: average of activated CD4+ and CD8+ T-lymphocytes (n = 3).Back to article page
