Used in immunological research to quantify rat CD73 antibody levels in biological samples such as serum, plasma, or cell culture supernatants. Enables detection and measurement of immune responses related to CD73, an enzyme involved in adenosine production and immune regulation. Commonly applied in studies of inflammation, autoimmune diseases, cancer immunology, and neurological disorders in rat models. Supports high-throughput screening and validation of therapeutic interventions targeting the CD73 pathway. Provides a reliable, sensitive, and specific method for monitoring changes in CD773 expression or antibody production in experimental settings.
