Used in biomedical research to detect and quantify Carboxypeptidase Q (CPQ) in human biological samples such as serum, plasma, and cell culture supernatants. This ELISA kit enables researchers to study CPQ's role in physiological and pathological processes, including immune regulation and inflammatory responses. It is particularly useful in clinical research settings for investigating kidney function and complement system activation, as CP7 is linked to the regulation of complement factor H. The assay provides high sensitivity and specificity, making it suitable for large-scale studies and diagnostic development.
