How to Store PNC-27: Temperature, Shelf Life & Handling
Storage requirements for PNC-27 follow from what the molecule actually is — membranolytic fusion peptide (32 residues): p53-derived domain + membrane-penetrating leader. The conditions below reflect that chemistry rather than generic peptide guidance.
Overview
Freezer sealed, fridge once mixed, and make fresh working dilutions close to when you use them.
What PNC-27 actually is
A designed peptide studied only in the lab, in cell culture, for a striking trick: it latches onto HDM-2 on certain cancer cells and pokes holes in their outer membrane, breaking those cells apart while reportedly leaving healthy cells alone.
Supplied for laboratory research use only — not for human or animal use.
Third-party tested by HPLC and LC-MS, ≥99% purity, with a Certificate of Analysis on every order. Ships across Canada.

Storage conditions for PNC-27
Why these conditions, specifically
Its membrane activity is the point of the molecule and also the reason it does not behave like a simple soluble peptide in handling.
The main route to be aware of: aggregation of the amphipathic chain at the air-liquid interface or high concentration.
All 3 degradation routes for PNC-27Freeze–thaw
Aliquot on first reconstitution; the amphipathic sequence is best not repeatedly frozen and thawed.
What PNC-27 is studied for
Studied for binding HDM-2 displayed on the surface of certain cancer cells in vitro.
Examined for forming transmembrane pores that lead to lysis of targeted cells in culture.
Investigated for a reported preference for tumour cells over normal cells in preclinical cell-culture models.
