Used to quantitatively measure human β-nerve growth factor (β-NGF) in biological samples such as serum, plasma, cerebrospinal fluid, and cell culture supernatants. Widely applied in neuroscience research to study neurodegenerative diseases like Alzheimer's and Parkinson's, where NGF levels are linked to neuronal survival and function. Helps assess nerve regeneration and neuroinflammation in clinical and preclinical studies. Also used in cancer research, as NGF plays a role in tumor progression and pain signaling. Provides high sensitivity and specificity for detecting low concentrations of β-NGF, enabling accurate biomarker analysis in diagnostic and therapeutic development.
