Used in biomedical research to measure PI3K enzyme activity in rat samples, this ELISA kit helps study signaling pathways involved in cell growth, metabolism, and survival. It is commonly applied in cancer research, diabetes studies, and neurodegenerative disease investigations where PI3K pathway dysregulation occurs. The kit enables researchers to evaluate the effects of drugs or experimental treatments on PI3K activity in rat models, supporting preclinical development and mechanistic studies.
