Neurogenesis
Hippocampal neurogenesis markers are primary studied endpoints.
Neurotrophins
Neurotrophic-factor expression is widely documented.
Cognition
Memory-related endpoints appear in behavioral models.
P21 is studied as a CNTF-derived neurogenic peptide. Research focuses on its potential to promote neurogenesis, upregulate neurotrophic factors, and influence DCX-positive neuronal markers in models.
P21 is a synthetic peptide studied for its potential to support neurogenesis and cognitive resilience.
“P21 is our go-to for neurogenesis-marker work. Consistent material makes the immunohistochemistry results comparable across runs.”

It is studied specifically for neurogenic endpoints derived from CNTF signaling, distinguishing it from monoamine-focused nootropic peptides.
