Used in biomedical research to measure levels of phosphoinositide 3 kinase (PI3K) in rat samples, this ELISA kit enables scientists to study the activation and regulation of the PI3K signaling pathway. It is commonly applied in studies related to cell growth, insulin signaling, cancer progression, and metabolic disorders. Researchers use it to evaluate how experimental treatments, drugs, or genetic modifications affect PI3K activity in tissues or cultured cells from rat models. The kit supports quantitative analysis, making it valuable for preclinical research and biomarker discovery.
