Used in research settings to quantify intestinal fatty acid binding protein (iFABP) levels in biological samples such as serum, plasma, or tissue homogenates. This assay is commonly applied in studies related to intestinal injury, including ischemia, necrotizing enterocolitis, inflammatory bowel disease, and gut barrier dysfunction. Due to the high specificity and sensitivity of the ELISA format, it enables early detection of enterocyte damage, making it valuable in clinical and preclinical investigations. Researchers also use this kit to monitor disease progression or evaluate therapeutic interventions targeting intestinal health.
