library_construction_protocol: The cells are bound to Concanavalin A-coated magnetic beads, and the cell membrane is permeabilized by Digitonin. The enzyme pA-Tn5 Transposase precisely binds the DNA sequence near the target protein under the antibody guidance and results in factor-targeted tagmentation. DNA sequence is tagmented, with adapters added at the same time at both ends, which can be enriched by PCR to form the sequencing-ready libraries. After the PCR reaction, libraries were purified with the AMPure beads.
