Western blot analysis is shown using GeneTex's Affinity Purified anti-p33 ING1 antibody to detect over expressed Human ING1 present in cell nuclear extracts. This western blot shows reactivity with purified recombinant GST tagged human ING1b (lane 1) and ING1c protein (lane 2). No reactivity is seen against GST or other ING proteins (not shown). Reactivity of this polyclonal antibody is similar to the specificity of a positive control monoclonal antibody (not shown). The blot was incubated with a 1:1,000 dilution of the antibody at room temperature followed by detection using standard techniques.
