Used in neuroscience research to quantify levels of human neuroprotective factor in biological samples such as cerebrospinal fluid, serum, or cell culture supernatants. Enables researchers to study the role of neuroprotective factors in neurodegenerative diseases like Alzheimer's, Parkinson's, and ALS. Supports investigation into neuroprotection mechanisms, neuronal survival, and potential therapeutic interventions. Commonly applied in preclinical studies, biomarker discovery, and drug development to assess changes in neuroprotective factor expression under various experimental or pathological conditions. Provides a reliable, sensitive, and specific method for detecting protein levels, aiding in the understanding of central nervous system health and disease progression.
