How to Read a PNC-27 Certificate of Analysis (COA)
A Certificate of Analysis is only useful if you know which number on it matters for the compound in front of you. For PNC-27, the informative checks are not the same as for a generic short peptide.
Overview
Confirm identity by weight and a clean trace; for a longer peptide, missing-piece impurities are the thing to check.
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.

Assays that are informative for PNC-27
What to check on the COA
Confirm identity by mass and check purity by RP-HPLC; for a 32-mer, deletion sequences are the characteristic synthesis impurity and should be resolved from the main peak.
Deletion and truncation sequences from incomplete coupling across the longer chain.

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.
Summarizes published preclinical literature. Provided for research reference only; not a claim of efficacy or a description of human use.
