Fig. S1
H3.3-bio is Present Sub-stoichiometrically to Endogenous H3.3 Protein (related to Figure 1) (A) cmlc2:H3.3-bio does not drive expression (green) in epicardium and endocardium. Both non-muscle cell types are recognized by an antibody against Raldh2 (arrows; red). Scale bar, 50 ?m. (B) Endogenous H3.3 is expressed in excess of transgenic H3.3-bio, which is undetectable using anti-H3.3 (lane 1). However, H3.3-bio can be detected from whole hearts using anti-FLAG (lane 2). Immunoprecipitation of H3.3-bio chromatin using the FLAG antibody enriches both forms of H3.3 (lane 3). |
