Used in biomedical research to detect and quantify intestinal fatty acid binding protein (I-FABP), a biomarker released during enterocyte damage. Helps assess intestinal injury in conditions such as necrotizing enterocolitis, inflammatory bowel disease, celiac disease, and ischemia-reperfusion injury. Commonly applied in clinical studies and preclinical models to evaluate gut barrier integrity and monitor response to therapeutic interventions. The ELISA format allows for high sensitivity and specificity in serum, plasma, and tissue homogenate samples, making it a valuable tool for gastrointestinal research.
