A guide to selecting high-performing antibodies for ARID2 (UniProt ID: Q68CP9) for use in western blot,...

The AT-rich interactive domain-containing protein 2 (ARID2) is a core component of the chromatin-remodeling complex that regulates transcription by modulating nucleosome positioning. Here we have characterized six ARID2 commercial antibodies for western blot, immunoprecipitation, and immunofluorescence using a standardized experimental protocol based on comparing read-outs in knockout cell lines and isogenic parental controls. These studies are part of a larger, collaborative initiative seeking to address antibody reproducibility issues by characterizing commercially available antibodies for human proteins and publishing the results openly as a resource for the scientific community. While the use of antibodies and protocols vary between laboratories, we encourage readers to use this report as a guide to select the most appropriate antibodies for their specific needs.
