FIGURE 3.

Comparison of SPF and non-SPF baboon serum IgM/IgG antibody binding and CDC to PBMCs from GTKO, GTKO/β4GalNT2KO, and TKO pigs. On the y axis, the dotted line represents the cut-off values (IgM 1.2, IgG 1.1, CDC 6.4%) below which there is no binding or CDC. The red lines indicate the mean values (**P < 0.01; ns = not significant). CDC, complement-dependent cytotoxicity; GTKO, α1,3-galactosyltransfearse gene-knockout; PBMCs, peripheral blood mononuclear cells; SPF, specific pathogen-free; TKO, triple-knockout.
