Cell type Class: Uterus
Cell type: Uterus
MeSH Description: The hollow thick-walled muscular organ in the female PELVIS. It consists of the fundus (the body) which is the site of EMBRYO IMPLANTATION and FETAL DEVELOPMENT. Beyond the isthmus at the perineal end of fundus, is CERVIX UTERI (the neck) opening into VAGINA. Beyond the isthmi at the upper abdominal end of fundus, are the FALLOPIAN TUBES.

library_strategy: ChIP-Seq
library_source: GENOMIC
library_selection: ChIP
library_construction_protocol: Cells were fixed with 1% formaldehyde for 15 min and quenched with 0.125 M glycine. Lysates were sonicated with a microtip sonicator to shear the DNA. Genomic DNA (Input) was prepared by treating aliquots of chromatin with RNase, proteinase K and heat for de-crosslinking, followed by ethanol precipitation. For each ChIP reaction, 30 ug of chromatin was precleared with protein A agarose beads (Invitrogen). ChIP reaction was set up using precleared chromatin and antibody and incubated overnight at 4 C. Protein A agarose beads were added and incubation at 4 C was continued for another 3 hr. Immune complexes were washed, eluted from the beads with SDS buffer, and subjected to RNase and proteinase K treatment. Crosslinks were reversed by incubation overnight at 65 C, and ChIP DNA was purified by phenol-chloroform extraction and ethanol precipitation. Illumina sequencing libraries were prepared from the ChIP and Input DNAs by the standard consecutive enzymatic steps of end-polishing, dA-addition, and adaptor ligation. After a final PCR amplification step, the resulting DNA libraries were quantified and sequenced on Illumina NextSeq 500.
