Used in biomedical research to quantify levels of GLUT1 protein in human biological samples such as serum, plasma, or cell lysates. This kit enables researchers to study glucose metabolism, insulin signaling, and cellular energy regulation. It is particularly valuable in diabetes research, cancer metabolism studies (since many cancer cells overexpress GLUT1), and neurological disorders where glucose transport across the blood-brain barrier is impaired. The assay supports high-throughput analysis with high sensitivity and specificity, making it suitable for both clinical research and drug development.
