Used in immunological research to quantify levels of lymphotactin (XCL1), a chemokine involved in T-cell and NK cell recruitment. The ELISA kit enables detection of Lptn/LTN/XCL1 in biological samples such as serum, plasma, or cell culture supernatants, supporting studies on immune response regulation, inflammation, and autoimmune diseases. Commonly applied in preclinical research, vaccine development, and cancer immunotherapy to assess chemokine expression patterns and immune cell trafficking. Provides a reliable, sensitive, and high-throughput method for measuring XCL1 concentration in rat models.
