Used in neuroscience and immunology research to quantify Ninjurin-2 protein levels in biological samples such as cell lysates, tissue homogenates, and cerebrospinal fluid. Enables investigation of nerve injury mechanisms, axonal degeneration, and inflammatory responses in the nervous system. Supports studies on neurodegenerative diseases, including multiple sclerosis and peripheral neuropathies, by providing a reliable method to monitor changes in Ninjurin-2 expression during disease progression or after therapeutic interventions. Also applied in cell signaling research to explore the role of Ninjurin-2 in cell adhesion, nerve regeneration, and immune cell migration.
