Used in biomedical research to quantify Protein Kinase A (PKA) activity in rat samples, this ELISA kit enables accurate measurement of PKA levels in cell lysates, tissue extracts, and biological fluids. It is widely applied in studies related to signal transduction pathways, particularly those involving cyclic AMP (cAMP), which regulates metabolism, gene expression, and cellular responses. Researchers use this kit to investigate hormonal regulation, neurological disorders, cardiovascular diseases, and cancer progression in rat models. The assay supports high-throughput screening and provides a reliable tool for evaluating the effects of drugs or experimental treatments on PKA signaling. Its sensitivity and specificity make it suitable for preclinical research and mechanistic studies in pharmacology and physiology.
