Used in biomedical research to quantify levels of galactosyltransferase α1,3 enzyme in mouse samples. Helps study immune responses related to carbohydrate antigens, particularly in xenotransplantation models where GGTA1 plays a role in producing the α-Gal epitope. Enables researchers to assess gene knockout efficiency or monitor expression changes in tissues and cells under experimental conditions. Widely applied in immunology, transplantation research, and functional genomics studies involving mouse models.
