Used for the quantitative measurement of ACK (Activated C-KIT) enzyme activity in rat biological samples such as serum, plasma, and cell culture supernatants. This ELISA kit enables researchers to assess ACK signaling pathways involved in cell proliferation, survival, and differentiation, particularly in studies related to cancer, stem cell biology, and immune response. It is commonly applied in preclinical research to evaluate the effects of pharmaceutical compounds or experimental treatments on ACK activity in rat disease models. The assay provides high sensitivity and specificity, allowing accurate detection of changes in ACK levels for reliable data analysis in biomedical research.
