Used in biomedical research to quantify rat erythropoietin receptor (EPOR) levels in biological samples such as serum, plasma, and tissue lysates. This ELISA kit enables researchers to study erythropoiesis, red blood cell regulation, and related signaling pathways in experimental models. It is particularly useful in studies involving anemia, hypoxia, and hematopoietic disorders in rats. The assay provides a sensitive and specific method for monitoring EPOR expression changes in response to therapeutic agents or disease conditions, supporting preclinical research and drug development.
