Used in biomedical research to detect and quantify levels of Trefoil Factor 1 (TFF1) in human biological samples such as serum, plasma, and cell culture supernatants. This ELISA kit is particularly valuable in studies related to gastrointestinal mucosal protection, inflammation, and cancer progression, as TFF1 plays a key role in epithelial repair and maintenance. It is widely used in clinical laboratories and research settings to investigate gastric diseases, including gastritis, gastric ulcers, and gastric carcinoma. The assay enables high sensitivity and specificity, allowing researchers to monitor disease markers and evaluate therapeutic responses in experimental models.
