            Figure 1: Western blot data
            Western Analysis of H3K4me3 dNuc. Top Panel: Unmodified (EpiCypher 16-0006; 
            Lane 1) and H3K4me3 (Lane 2) nucleosomes were probed with an anti-H3K4me3 
            antibody and analyzed via ECL readout. Only the H3K4me3 sample produced a 
            detectable signal. Bottom Panel: Detail from Coomassie stained gel showing unmodified 
            (Lane 1) and H3K4me3 (Lane 2) nucleosomes.

            Figure 3: Protein gel data
            Coomassie stained SDS-PAGE gel of proteins in H3K4me3 dNuc (1 µg) demonstrates 
            the purity of histones in the preparation. Sizes of molecular weight markers and positions 
            of the core histones (H2A, H2B, H3K4me3 and H4) are indicated.
