Used in neuroscience and biomedical research to quantify levels of Ciliary Neurotrophic Factor (CNTF) in biological samples such as serum, plasma, cerebrospinal fluid, and cell culture supernatants. This ELISA kit helps investigate the role of CNTF in neuronal survival, differentiation, and protection, particularly in studies related to neurodegenerative diseases like amyotrophic lateral sclerosis (ALS), spinal cord injury, and peripheral neuropathies. It is also applied in preclinical drug development to assess the efficacy of therapeutic agents targeting neurotrophic pathways. The assay provides a sensitive and specific means to monitor changes in CNTF expression under experimental conditions, supporting both basic research and translational studies.
