shows the normalized bacterial signal. In C – F IgG1, IgGh 17, 32, and, 47 hinge variants are assessed. The phagocytosis score in E – F is normalized to Ab25 IgG1’s phagocytosis score for each individual experiment ( N = 4 independent experiments). Data in B – G are from N = 4 independent experiments. The mean is shown in all panels, and the error bars are SEM.
