ChIP-seq of old and new H3.3 in RPE1-hTERT cells

On of the H3.3 genes (H3F3B) was C-terminally tagged with a recombination-induced tag exchange (RITE) tag in human RPE1-hTERT cells to follow old (V5 tag) and new (FLAG tag) H3.3 and measure the dynamics of H3.3. New H3.3 was induced by activating Cre recombinase with 4-hydrotamoxifen (4OHT). ChIP-seq was done on old H3.3 and new H3.3 8h and 24h after 4OHT treatment.
