Used in biomedical research to quantify Dickkopf-1 (DKK1) protein levels in rat biological samples such as serum, plasma, and cell culture supernatants. This ELISA kit is particularly useful in studies related to bone metabolism, osteoporosis, and Wnt signaling pathway regulation. It enables researchers to assess DKK1's role in diseases involving abnormal bone formation, cancer progression, and metabolic disorders in rat models. The assay provides a sensitive and specific measurement, supporting high-throughput analysis in preclinical studies and therapeutic development.
