Identification of MEIS2 binding sites through ChIP-seq in the neuroblastoma Kelly and BE(2)-C cell lines.. Identification of MEIS2 binding sites through ChIP-seq in the neuroblastoma Kelly and BE(2)-C cell lines.

In total, 100x106 SK-N-BE(2)-C and Kelly neuroblastoma cells were processed for ChIP-sequencing. Briefly, pellets were prepared by fixing cells in 1% formaldehyde for 15 minutes, and quenching in 1M Tris pH 7.5. Nuclei were prepared using the Sigma Nuclei Isolation Kit (#NUC-101), and sonicated using a Branson digital sonifier as previously. Antibodies to MEIS2 were from Sigma Aldrich (HPA003256). ChIP-seq libraries were prepared using the KAPA HyperPrep ChIP library kit following the manufacturer’s settings, and were sequenced on an Illumina NextSeq 500 machine.
