a, silver-stain of affinity-purified cBAF complexes from mammalian HEK293T cells expressing HA-DPF2. b, Schematic of XbaI accessibility assay with extended arrays and cBAF remodeling complex. c, Agarose gel visualization of XbaI accessibility assay of extended nucleosome arrays (no linker histone) incubated without and with cBAF plus ATP. d, Schematic of DNase I digestion analysis of transcription factors and cBAF with H1-compacted arrays. e, DNase I digestion analysis H1-compacted nucleosome arrays incubated alone (no TF, lanes 2 and 5), PU.1 alone (lanes 3 and 6), and PU.1 with cBAF and ATP (lanes 4 and 7). The same samples were used to perform nanopore sequencing shown in Fig. 3b.
