Description
P21 5mg (also known as P021) is a high-purity, research-grade synthetic tetrameric peptide sequence derived from the active region of ciliary neurotrophic factor (CNTF). It is commonly examined in preclinical and in vitro investigations focused on enhancing neurogenesis, synaptic density, and cognitive pathway signaling without inducing systemic immunogenicity or non-specific CNTF side effects. It is widely used in laboratory environments to study the biochemical mechanisms of neurotrophic factor upregulation, amyloid-beta cytotoxicity mitigation, and the stabilization of tau phosphorylation dynamics.
Its well-characterised capability to cross biological barriers and promote dentate gyrus progenitor cell differentiation makes it a valuable tool for analysing synaptic plasticity, memory formation mechanics, and molecular pathways related to neurodegenerative disorder models and brain aging research. This compound is supplied in a lyophilised form suitable for controlled research applications.
