Used to detect and quantify LGMN (legumain) enzyme activity in mouse biological samples such as serum, plasma, tissue lysates, and cell culture supernatants. This ELISA kit is specifically designed to measure active forms of LGMN, which plays a role in antigen processing, tumor progression, and inflammatory diseases. It is widely applied in immunological research, cancer studies, and drug development where monitoring LGMN activity helps assess disease mechanisms and therapeutic responses. The assay enables high-throughput, sensitive, and specific measurement, making it suitable for preclinical studies involving mouse models.
