Used in biomedical research to quantitatively measure insulin-like growth factor 2 (IGF-2) levels in rat biological samples such as serum, plasma, and tissue lysates. This kit is essential for studying growth regulation, fetal development, and metabolic processes in rat models. It is widely applied in endocrinology, developmental biology, and cancer research where IGF-2 plays a role in cell proliferation and survival. The assay supports high sensitivity and specificity, enabling accurate detection of IGF-2 concentration changes in experimental conditions.
