Used in biomedical research to quantify levels of human glutamine transferase (TG) in biological samples such as serum, plasma, or cell lysates. This ELISA kit enables researchers to study the enzyme's role in cellular processes including apoptosis, extracellular matrix formation, and signal transduction. It is particularly valuable in investigating diseases where TG activity is altered, such as celiac disease, neurodegenerative disorders, and certain cancers. The assay provides a sensitive and specific measurement, supporting both clinical research and drug development efforts focused on transglutaminase pathways.
