title: GSM9269054: CATCH_H3K9me3_AG_rep1; Mus musculus; ChIP-Seq
library_construction_protocol: BDF1(C57BL/6×DBA2) ×JF1/Ms zygotes were selected 10 h after fertilization (late G2 or PN5 stage). Zygotes were collected in 9 µL of Nuclei EZ lysis buffer (Sigma, NUC-101) supplemented with a complete EDTA-free protease inhibitor cocktail and 1 mM phenylmethanesulfonyl fluoride. CATCH-seq libraries were prepared as previously described (Zhu, Y et al.,).
