Abstract

Casein kinase II subunit alpha (CSNK2A1), a serine/threonine kinase, phosphorylates multiple protein substrates and is involved in diverse cellular and biological processes. Implicated in various human diseases, high-performing antibodies would help evaluate its potential as a therapeutic target and benefit the scientific community. In this study, we have characterized ten CSNK2A1 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 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.
