Peptide Array - Anti-gamma H2A.X (phospho S139) antibody [N1-431] (AB303656)

Peptide array analysis of ab303656 at 0.05 µg/ml followed by a Goat Anti-Rabbit IgG, (H+L), Fluor 647nm conjugated at 1/50,000 dilution. All batches of ab303656 are tested in Peptide Array against 501 different modified and unmodified histone peptides; each peptide is printed on the array at six concentrations (each in triplicate). Circle area represents affinity between the antibody and a peptide : all antigen-containing peptides are displayed as red circles, all other peptides as blue circles. The affinity is calculated as the area under the curve when antibody binding values are plotted against the corresponding peptide concentration. Each circle area is normalized to the peptide with the strongest affinity. The complete dataset, including a full list of all peptides and information on the position of each peptide in the diagram, can be downloaded here.
