Figure 1: Western blot data

Western Analysis of Nucleosome, Recombinant Human, H2BK120ub. 

Top Panel: Unmodified H3 (Lane 1) and H2BK120ub containing nucleosomes 

(Lane 2) were probed with an anti-H2BK120ub antibody and analyzed via ECL

 readout. Only the H2BK120ub sample produced a detectable signal. Bottom 

Panel: Detail from Coomassie stained gel showing unmodified nucleosomes 

(Lane 1) and H2BK120ub nucleosomes (Lane 2).
