Used in biomedical research to quantify fibroblast-specific protein 1 (FSP1) levels in biological samples such as tissue lysates or cell culture supernatants. Enables researchers to study fibroblast activation and epithelial-mesenchymal transition (EMT) in processes like tissue fibrosis, wound healing, and cancer progression. Commonly applied in studies of organ fibrosis including lung, liver, and kidney diseases. Supports investigation into the role of FSP1-positive cells in inflammation and tumor microenvironment. Provides a reliable, sensitive, and specific method for detecting FSP1 in experimental models, aiding in the development of potential therapeutic targets.
