Description
PNC-27 is a 32-amino-acid synthetic peptide widely used as a reference compound in oncology and membrane-biology research. It combines a p53-derived sequence (residues 12-26) with a membranolytic segment, and is studied in vitro for its reported interaction with membrane-associated MDM2 in various cancer cell-line models.
Supplied as a lyophilized powder, ≥95% by HPLC, in a sealed glass vial. Intended solely for laboratory and in-vitro research.
For research purposes only. Not for human consumption, ingestion, or any therapeutic, diagnostic or clinical use. No medical claims are made and no safety or efficacy in humans is implied.

Peptides in lyophilized (freeze-dried) form are shipped in sealed glass vials using standard delivery methods and do not require refrigeration during transit. Lyophilized peptides are highly stable at ambient temperatures for the duration of standard shipping (typical transit windows are shown at checkout). Once received, transfer the product to refrigerated storage (2–8°C) promptly.
Frequently Asked
Research peptides are supplied in lyophilized (freeze-dried) form. The amount of material is typically only a few milligrams — appearing as a very thin film or small pellet at the bottom of the vial, often nearly invisible. This is completely normal.
Unlike some suppliers who add bulk fillers (such as Mannitol), CertaPeptides provides pure peptide without unnecessary additives.
