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.
