Figure

Immunoblots of lysates generated from parental and sgDnmt3a mESCs ectopically expressing HA-tagged DNMT3A2. Vinculin was used as a loading control. Endogenous expression of the long isoform (DNMT3A1) and short isoform (DNMT3A2) are indicated. Please see Extended Data Figure 3a in the article [1].
