How Long Does PNC-27 Last? Shelf Life & Stability
"Stable" is meaningless without saying stable against what. PNC-27 has its own set of degradation routes, and they determine which storage precautions actually matter for it.
Overview
Best not frozen and thawed repeatedly; it can gather at the liquid surface and clump.
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.

Degradation routes specific to PNC-27
- Aggregation of the amphipathic chain at the air-liquid interface or high concentration.
- Adsorptive loss to plasticware.
- Deletion-sequence content from synthesis of a longer peptide.
Its membrane activity is the point of the molecule and also the reason it does not behave like a simple soluble peptide in handling.
Freeze–thaw tolerance
Aliquot on first reconstitution; the amphipathic sequence is best not repeatedly frozen and thawed.
How storage addresses these routes
Practical window once reconstituted: Short — prepare working solutions close to use.
Full PNC-27 storage conditionsWhat PNC-27 is studied for
Studied for binding HDM-2 displayed on the surface of certain cancer cells in vitro.
