Abstract
Superoxide dismutase [Cu-Zn] 1 (SOD1), is an antioxidant enzyme encoded by the gene SOD1, responsible for regulating oxidative stress levels by sequestering free radicals. Identified as the first gene with mutations in Amyotrophic lateral sclerosis (ALS), SOD1 is a determinant for studying diseases of aging and neurodegeneration. With guidance on well-characterized anti-SOD1 antibodies, the reproducibility of SOD1 research would be enhanced. In this study, we characterized eleven SOD1 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. We identified many high-performing antibodies and encourage readers to use this report as a guide to select the most appropriate antibody for their specific needs.
