Used in neuroscience and biomedical research to quantify ciliary neurotrophic factor (CNTF) levels in rat biological samples such as serum, plasma, cerebrospinal fluid, and tissue homogenates. This ELISA kit enables researchers to study the role of CNTF in neuronal survival, differentiation, and protection, particularly in models of neurodegenerative diseases like amyotrophic lateral sclerosis (ALS), spinal cord injury, and peripheral neuropathies. It is also applied in preclinical studies evaluating neuroprotective therapies, allowing for accurate measurement of CNTF expression changes in response to experimental treatments. The assay supports high-throughput analysis with high sensitivity and specificity, making it a valuable tool in both academic and pharmaceutical research settings.
