特異性：Cytokeratin 8 (Phospho-Ser431) antibody detects endogenous levels of Cytokeratin 8 only when phosphorylated at serine 431.
純度：Affinity-purified fromrabbit antiserum by affinity-chromatography using epitope-specific phosphopeptide. The antibody against non-phosphopeptide was removed by chromatography using non-phosphopeptide corresponding to the phosphorylation site.
形状：Rabbit IgG in phosphate buffered saline (without Mg2+ and Ca2+), pH 7.4, 150mM NaCl, 0.02% sodium azide and 50% glycerol.
