Used in biomedical research to quantify Galectin-4 protein levels in biological samples such as cell lysates, tissue extracts, and serum. Enables investigation of Galectin-4's role in gastrointestinal diseases, cancer progression, and immune regulation. Supports studies on inflammatory bowel disease and colorectal cancer due to Galectin-4's expression in the digestive tract. Provides a reliable, sensitive, and specific method for detecting low concentrations of Galectin-4, aiding in biomarker discovery and therapeutic development.
