Research Applications
- Intranasal Drug-Delivery Research: PT-141 formulations are studied to characterize melanocortin-agonist transport across nasal mucosa. Research parameters include absorption kinetics, systemic bioavailability, metabolic stability, and comparative pharmacokinetic profiles across intranasal and subcutaneous delivery models.
- Neurobehavioral Research: Intranasal PT-141 is investigated for its influence on MC3R- and MC4R-associated central arousal pathways. Studies examine CNS biodistribution, receptor engagement, signaling intensity, onset kinetics, and relationships between systemic exposure and neurobehavioral endpoints.
- Pharmaceutical Sciences: PT-141 intranasal formulations are evaluated to optimize peptide stability and delivery characteristics. Research examines spray volume, droplet-size distribution, pH, excipient compatibility, mucosal retention, peptide integrity, and formulation stability.
Storage Conditions
Unreconstituted
Store at -20°C to 4°C (freezer or refrigerator). Stable for 24+ months.
Reconstituted
Refrigerate at 2–8°C. Use within 30 days for optimal stability.
Avoid
Repeated freeze-thaw cycles, direct sunlight, and temperatures above 25°C.
Safety & Compliance
- Wear nitrile gloves and safety goggles when handling research compounds.
- Work in a clean, controlled environment (laminar flow hood recommended).
- Dispose of sharps and used materials in approved biohazard containers.
- This product is for laboratory research use only (RUO) — not for human or veterinary use.
Quality Assurance Standards
Each production lot is subjected to rigorous analytical evaluation to meet pharmaceutical-grade specifications. Full testing results and procedural documentation are furnished through the accompanying Certificate of Analysis (COA) with every shipment.
Certificate of Analysis
Latest COA for PT-141 (Spray) — independently tested via HPLC and Mass Spectrometry.
Testing Methodology
Every batch undergoes a multi-stage analytical pipeline before release. Results are compiled into the Certificate of Analysis (COA) included with each order.
- • HPLC — High-Performance Liquid Chromatography confirms peptide purity ≥98%.
- • Mass Spectrometry — Validates molecular identity and correct sequence.
- • Endotoxin (LAL) — Limulus Amebocyte Lysate assay ensures endotoxin levels are within safe limits.
- • Sterility — Microbial contamination testing per USP standards.
