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.

library_construction_protocol
For ChIP-seq analysis using the Illumina HiSeq 2000 or HiSeq 2500, 10-20 ng of ChIP DNA was processed for library generation using the ChIP-seq Sample Preparation Kit (Illumina) following the manufacturer's protocol. Raw ChIP-seq data were processed using the Illumina software pipeline. Only ChIP-seq reads that aligned to exactly one location in the reference human genome (UCSC hg18) were retained for downstream data analysis.
