(C) IF of DAXX in PN5 stage pronuclei of zygotes expressing CBX2-EGFP (n=9) or CBX2F12A-EGFP (n=17). mRNAs (100ng/µl) were injected into mouse PN2 stage zygotes. Yellow dashed circles represent the contours of the pronuclei.. Data information: Panels C: Paternal and maternal pronuclei of a given condition originate from same zygotes. All scale bars 10µm.
