A Coomassie blue staining of a PVDF membrane after an immunoprecipitation experiment using cell nuclei of 1 × 1010 HeLa cells with Ki-S2. The 100-kD protein band of this experiment was excised and used for digestion with Lys C and peptide sequencing. Molecular weight standards are shown on the right (in kilodaltons).
