Used in biomedical research to detect and quantify the levels of the PI3K p85 regulatory subunit in mouse samples. This ELISA kit enables researchers to study the activation and regulation of the PI3K signaling pathway, which plays a critical role in cellular processes such as growth, proliferation, survival, and metabolism. It is commonly applied in studies related to cancer, diabetes, immunology, and neurodegenerative diseases using mouse models. The kit provides a reliable and sensitive method for measuring p85 protein levels in cell lysates, tissue homogenates, and biological fluids, supporting mechanistic investigations and therapeutic development.
