Used in biomedical research to quantify levels of progranulin (PGRN) in biological samples such as serum, plasma, and cell culture supernatants. Widely applied in studies related to neurodegenerative diseases, particularly frontotemporal dementia (FTD), where PGRN deficiency is a known genetic factor. Helps researchers assess PGRN expression in inflammatory conditions, cancer, and autoimmune disorders due to its role in cell growth, wound healing, and immune regulation. The kit enables high-throughput, accurate measurement, supporting both clinical investigations and drug development efforts targeting PGRN pathways.
