Chromatin at the c-fms promoter is in a partially active conformation in B cells. (A) From left to right: In vivo MNase footprinting experiment with naked DNA and chromatin prepared from the indicated cell populations using primers specific for the c-fms promoter (upper panel) or the GAPDH promoter (lower panel). Horizontal arrows indicate the position of transcription start sites. The PvuII site is at position −66 bp. (B) In vivo DNaseI footprinting experiment with naked DNA and the indicated cell populations using increasing amounts of DNaseI (20 and 40 U) G: G-reaction of naked DNA. For further description, see Figure 3.
