Used in neuroscience research to quantify levels of Neurotrophic Factor 4 (NT-4) in mouse biological samples such as serum, plasma, cell culture supernatants, and tissue homogenates. This ELISA kit enables researchers to study the role of NT-4 in neuronal survival, differentiation, and synaptic plasticity. It is particularly useful in studies related to neurodegenerative diseases, nerve injury, and brain development. The assay provides a sensitive and specific method to monitor changes in NT-4 expression under experimental conditions, supporting investigations into neurotrophic signaling pathways and potential therapeutic interventions.
