P-21 Peptide Vial For Sale

P-21 Peptide Vial is a premium-grade, lyophilized research peptide available exclusively for laboratory and scientific investigation. Supplied at ≥98% purity and rigorously verified through HPLC and mass spectrometry analysis, this compound is positioned as a reliable tool for qualified researchers exploring neurotrophic mechanisms and cognitive biology. For research use only. Not for human or veterinary use. Not for clinical, diagnostic, or consumptive applications.

Product Overview

P-21 is a short synthetic peptide derived from Ciliary Neurotrophic Factor (CNTF), a naturally occurring protein recognized for its role in neuronal survival, repair, and maintenance. As a CNTF analogue incorporating an adamantane moiety, P-21 has become a subject of considerable interest in the neuroscience research community. Scientists investigating neurogenesis, synaptic plasticity, and cognitive enhancement models frequently select P-21 for its consistent formulation and well-characterized biochemical profile. Direct Anti Peptide is proud to offer this compound to verified research professionals seeking dependable, high-quality peptide reagents.

Peptide Structure & Amino Acid Sequence

P-21 is a small tetrapeptide analogue of CNTF, engineered to retain the biologically relevant domain of the parent protein while incorporating structural modifications — notably the addition of an adamantane group — that confer enhanced stability and membrane permeability. This structural design enables the peptide to engage neurotrophic signaling pathways more efficiently than longer native sequences, making it a compact yet functionally significant research tool. Its molecular architecture supports investigations into BDNF upregulation, neurotrophin receptor interactions, and downstream neuroprotective signaling cascades.

Chemical & Physical Characteristics

• Classification: Synthetic CNTF-derived neurotrophic peptide
• Modification: Adamantane-conjugated tetrapeptide
• Physical Form: Lyophilized white to off-white powder
• Solubility: Soluble in aqueous buffers and standard laboratory solvents (for in vitro research use only)
• Molecular Weight: Low molecular weight; exact value available upon request with certificate of analysis
• Storage Stability: Enhanced by lyophilization; suitable for long-term archival under appropriate laboratory conditions

Purity & Analytical Verification (HPLC & MS)

Every batch of P-21 Peptide Vial offered at Direct Anti Peptide is manufactured to a minimum purity standard of ≥98%, confirmed through two complementary analytical techniques. High-Performance Liquid Chromatography (HPLC) is employed to assess chromatographic purity and detect any residual impurities or synthesis by-products. Mass Spectrometry (MS) independently confirms the correct molecular mass and structural identity of the compound. Researchers can request a Certificate of Analysis (CoA) at the time of ordering to verify these quality benchmarks for their specific batch.

Quality Control & Lyophilization Integrity

The lyophilization process — freeze-drying under controlled vacuum conditions — is central to the long-term integrity of P-21 peptide vials. By removing residual moisture, lyophilization dramatically reduces the risk of hydrolytic degradation and microbial contamination during storage and transit. Each vial is sealed under sterile conditions to maintain product integrity from manufacture through to laboratory receipt. The result is a stable, reproducible reagent that performs consistently across experimental replicates, a critical requirement for rigorous scientific investigation.

Safety, Handling & Laboratory Precautions

P-21 Peptide Vial is intended exclusively for use by trained research professionals operating within appropriately equipped laboratory environments. Standard laboratory safety protocols must be observed at all times when handling this compound. Appropriate personal protective equipment (PPE), including gloves, eye protection, and lab coat, should be worn. This product is not approved for any human or animal administration, and must not be used outside of a controlled research setting. Researchers should consult applicable institutional biosafety guidelines and local regulatory frameworks prior to use.

Reconstitution, Packaging & Storage

P-21 is supplied as a lyophilized powder in a sterile glass vial, designed to facilitate straightforward reconstitution in a laboratory setting using appropriate research-grade solvents as determined by the investigator’s experimental protocol. Reconstitution procedures should be performed under sterile conditions by qualified personnel. Upon receipt, vials should be stored according to the conditions specified on the accompanying CoA — typically at low temperature, away from light and moisture. Proper storage conditions are essential to preserve peptide integrity and ensure consistent experimental outcomes across studies.

Intended Research Use & Market Positioning

P-21 peptide is widely utilized in preclinical neuroscience research, particularly in studies examining neurogenesis, synaptic plasticity, BDNF modulation, and models relevant to neurocognitive conditions including Alzheimer’s disease research frameworks. Its CNTF-derived structure positions it as a valuable investigative tool for researchers focused on neurotrophic signaling, neuroprotection, and cognitive biology. Direct Anti Peptide supplies this compound strictly as a laboratory research reagent, with no implied therapeutic, diagnostic, or clinical application.
