- cFos expression is induced by neuronal activity and many other non-related factors
- Npas4 protein expression provides a pure marker of neuronal activity
- Our anti-Npas4 recombinant monoclonal antibody can help you avoid ambiguous results
Why Npas4?
• GPCR-mediated elevations in cAMP, neurotrophins and other paracrine factors all drive cFos expression in neurons and non-neuronal cells
• Npas4 is unique among IEG products in that expression is neuron-specific, has faster kinetics and is tuned exquisitely to Ca2+ signaling downstream of neuronal activity
Antibody Validation
• Our monoclonal antibody was raised against a large Npas4 protein fragment and selected among 100’s of clones for specificity as demonstrated by complete loss of reactivity in npas4 KO mice
• Validated in many diverse applications in multiple species
