MeSH Description
Immature, nucleated ERYTHROCYTES occupying the stage of ERYTHROPOIESIS that follows formation of ERYTHROID PRECURSOR CELLS and precedes formation of RETICULOCYTES. The normal series is called normoblasts. Cells called MEGALOBLASTS are a pathologic series of erythroblasts.

Cells were crosslinked with 1% formaldehyde for 10 minutes at room temperature. Fixed cells were lysised in 1mL Cell Lysis Buffer (10mM Tris-HCl pH 8, 10mM NaCl, 0.2% NP-40/Igepal). Nuclei were collected and lysised in 1mL Nuclear Lysis Buffer (50mM Tris-HCl pH 8, 10mM EDTA pH 8, 1% SDS). Chromatin was sonicated at 4 degrees C (Epishear, Active Motif). Chromatin was incubated with antibody and then decrosslink at 65C overnight. Libraries were prepared using TruSeq ChIP-seq Sample Preparation Kit (Part# IP-202-1012) according to Illumina's instructions.
