Spermatocytes

MeSH Description

Male germ cells derived from SPERMATOGONIA. The euploid primary spermatocytes undergo MEIOSIS and give rise to the haploid secondary spermatocytes which in turn give rise to SPERMATIDS.

library_construction_protocol

All sorted cells and H3K9me3 antibody incubated by magnetic beads were immunoprecipitated and DNA was finally isolated. The amount of DNA used for the ChIP: 6pg. The sequence libraries were generated using the KAPA Hyper Prep Kit for the Illumina platform (kk8504), following the manufacturer's instructions. Paired-end 150-bp sequencing was performed on Illumina HiSeq X10.
