CUT&Tag analysis was performed using the Hyperactive® Universal CUT&Tag Assay Kit for Illumina (Vazyme, TD903) as described by the manufacturers with some modifications. Briefly, nuclei were extracted from the 10,000 fresh cells, and added the ConA beads incubating at room temperature for 10 min. The mixed complexes were the incubated with antibodies with IgG antibody as a control, and the next day, followed by the secondary antibody. A diluted pA-Tn5 adapter complex was then added to the above system and incubated at room temperature for 1 h. After extensive washing, system were subsequently sheared by adding 5 × TTBL. Subsequent proteinase K and DNA extract beads were used for obtaining eluted DNA. Finally, the sequencing libraries were established after 12 cycles of PCR amplification and sequenced using Illumina Novaseq 6000 with paired-end 2x150 as the sequencing mode.
