Used in biomedical research to quantify human colony-stimulating factor (CSF) levels in biological samples such as serum, plasma, and cell culture supernatants. This ELISA kit enables researchers to study immune system regulation, hematopoiesis, and inflammatory responses. It is widely applied in preclinical studies involving cancer, infectious diseases, and autoimmune disorders to monitor CSF expression as a biomarker of immune activation or therapeutic response. The assay provides high sensitivity and specificity, making it suitable for detecting low concentrations of CSF in small sample volumes. Commonly used in laboratory settings for immunoassay development, drug discovery, and clinical research.
