P21 Nasal Spray — Pre-Mixed Research Peptide P21 Nasal Spray supplies 10mg of P21 in a pre-mixed 15mL intranasal format for laboratory research. P21 is a small peptide derived from ciliary neurotrophic factor (CNTF), studied in preclinical models of neurogenesis, synaptic plasticity and neurotrophic signaling. For laboratory research use only — not for human or veterinary use. What Is P21? P21 was developed as a blood-brain-barrier-relevant CNTF mimetic and is investigated in research on dentate gyrus neurogenesis, synaptic protein expression and memory-related models. Intranasal administration is a standard delivery route in this research area, which the pre-mixed spray format supports without reconstitution.
