V5 epitope tag-specific EBF1 ChIP and input (top, Schwickert et al., 2014), ChIP for endogenous Ikaros using the C-terminal Ikaros antibody employed in this study (Bossen et al., 2015; Ferreiros-Vidal et al., 2013), HA-tagged Ikaros using a HA epitope tag-specific reagent (Ferreiros-Vidal et al., 2013) and input (Ferreiros-Vidal et al., 2013) show binding of EBF1 and Ikaros to the Igll1 promoter.
