Used in neuroscience research to quantify Human Neurotrophic Factor 4 (NT-4) levels in biological samples such as serum, plasma, cerebrospinal fluid, and cell culture supernatants. The kit enables researchers to study the role of NT-4 in neuronal survival, differentiation, and synaptic plasticity. It is commonly applied in studies related to neurodegenerative diseases like Alzheimer's and Parkinson's, as well as nerve injury and regeneration. The assay supports high sensitivity and specificity, making it suitable for detecting low concentrations of NT-4 in small sample volumes. Widely used in academic labs, pharmaceutical research, and clinical studies investigating neurotrophic signaling pathways.
