Binding activity to the Id2 promoter in immature and mature B cells. Control or CD74−/− B cells extracts were subjected to EMSA using labeled probes representing the Id2 or Oct-1 promoters in the presence or absence of unlabeled Id2 probes (34-fold excess [B and C] or 74-fold excess [A–C]). The probes used were CAAATG (A), CACATG (B), and CACGTG (C). Arrows indicate complexes of proteins and probes. Results presented are representative of at least three separate experiments.
