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.
