PNC-27 is a research compound. It is not approved by the FDA or any regulatory body for human use. This article is for educational and informational purposes only. Nothing here constitutes medical advice. Consult a qualified physician before considering any peptide use.
Lyophilized (freeze-dried) PNC-27 should be stored at -20°C for long-term stability. Once reconstituted with bacteriostatic water, store at 2-8°C (refrigerated) and use within 4-6 weeks. Never freeze reconstituted peptides.
How Do You Store PNC-27?
Proper storage is critical for maintaining PNC-27's potency and safety. As a Cell-penetrating therapeutic peptide, PNC-27 is sensitive to heat, light, and moisture — improper storage can render it ineffective or harmful.
How Do You Store Lyophilized PNC-27?
Unreconstituted (freeze-dried) PNC-27: Store at -20°C (standard freezer) for maximum shelf life of 12-24+ months. Keep the vial sealed and away from moisture.
Room temperature storage is acceptable for short periods (shipping) but degrades potency over weeks. Refrigerator (2-8°C) storage extends this to several months.
How Do You Store Reconstituted PNC-27?
After mixing with bacteriostatic water: Store at 2-8°C (standard refrigerator). Use within 4-6 weeks for optimal potency.
Never freeze reconstituted PNC-27. Freezing and thawing damages the peptide structure. The bacteriostatic water's benzyl alcohol preservative is what allows the 4-6 week window — sterile water would give you only days.
Keep the vial upright and away from the refrigerator door (temperature fluctuations from opening/closing).
How Do You Know if PNC-27 Has Gone Bad?
Reconstituted PNC-27 should be clear and colorless. If you see cloudiness, particles, or discoloration — discard it. These indicate bacterial contamination or peptide degradation.
If stored properly, degradation is gradual and may not be visually apparent. This is why the 4-6 week window for reconstituted peptides exists.
Can You Travel With PNC-27?
Lyophilized PNC-27 can be shipped with cold packs and insulation. For short trips, a small cooler bag with an ice pack maintains adequate temperature.
Reconstituted PNC-27 is more temperature-sensitive and should be kept refrigerated during travel if possible.
Bottom Line on PNC-27 Storage
Freeze-dried: -20°C, sealed, 12+ months. Reconstituted: 2-8°C, use within 4-6 weeks, never freeze. Source from vendors who ship with proper cold-chain packaging.

Frequently Asked Questions
What is PNC-27?
PNC-27 (PNC-27 (p53-penetratin chimeric peptide)) is a Cell-penetrating therapeutic peptide. 32-residue chimeric peptide combining an HDM-2 binding domain from p53 with a cell-penetrating penetratin sequence. It is researched for broad-spectrum cancer cell killing, p53-independent mechanism, minimal normal cell toxicity, rapid killing kinetics (90 minutes).
What is the recommended PNC-27 dosage?
Common dosages: >10 mcg/mL (in vitro effective concentration); clinical dosing not established administered not established for human use via local application (proposed: nebulizer, suppository, IV at tumor site). Cycle length: unknown; 90-minute killing kinetics in vitro. Half-life: not established. Use our peptide calculator for exact reconstitution math.
What are the side effects of PNC-27?
Limited safety data. No apparent toxicity to normal tissue in culture. Potential immune responses to foreign peptide.
Is PNC-27 safe?
PNC-27 has shown a preliminary safety profile in research. Not FDA-approved in USA. Clinical trials conducted internationally. Research use only in US. All research should follow appropriate safety protocols.
