Used in neuroscience research to quantify levels of neural growth factor (NGF) in monkey brain tissue, cerebrospinal fluid, or cell culture samples. Enables study of neurodegenerative diseases such as Alzheimer's, Parkinson's, and spinal cord injuries by measuring NGF expression changes. Supports evaluation of therapeutic interventions targeting nerve regeneration and neuroprotection. Commonly applied in preclinical studies involving non-human primates to assess nervous system development, neuroinflammation, and response to experimental drugs. Provides high sensitivity and specificity for detecting low concentrations of NGF, aiding in understanding neurotrophic support mechanisms in the central and peripheral nervous systems.
