P21 – 10mg

P21 is a synthetic 15-amino-acid peptide fragment designed for laboratory investigation of neurotrophic biochemical mechanisms, neuropeptide signaling, and intracellular regulatory pathways associated with neuronal growth-factor modulation. Its design is structurally inspired by peptide domains involved in BDNF-related signaling. Foundational reference data for P21 and related neuroactive fragments are documented under PMID: 21238465, detailing peptide-induced neurotrophic responses in controlled research models.

In vitro, P21 is used to explore neuronal differentiation pathways, peptide–receptor interactions, intracellular second-messenger cascades, and structural effects on neurotrophic regulatory mechanisms. Due to its defined amino acid sequence and reproducible biochemical profile, P21 is suitable for mechanistic assays examining peptide-modulated signaling and neurochemical pathway mapping.

Supplied as a high-purity lyophilized peptide, P21 provides consistent preparation for neuronal pathway research, receptor-binding modeling, and biochemical characterization under controlled laboratory conditions.
