Used in biomedical research to quantify GADD45A protein levels in cell or tissue lysates, this ELISA kit enables scientists to study cellular stress responses, DNA damage repair mechanisms, and apoptosis regulation. It is widely applied in cancer research, toxicology studies, and drug development to assess how genotoxic stressors or therapeutic compounds influence GADD45A expression. The assay provides a sensitive and specific means to monitor changes in GADD45A under experimental conditions, supporting investigation into signaling pathways such as p53 and MAPK.
