Used in biomedical research to quantify levels of intestinal fatty acid binding protein (FABP2) in mouse samples, aiding in the study of intestinal health and injury. Commonly applied in research on inflammatory bowel disease (IBD), gut barrier function, and ischemia-reperfusion injury. Enables researchers to assess enterocyte damage and monitor disease progression or therapeutic response in experimental models. Provides a sensitive and specific method for detecting FABP2 in serum, plasma, or tissue homogenates, supporting high-throughput analysis in preclinical studies.
