What is PNC-27?

PNC-27 links residues 12-26 of the p53 tumor-suppressor protein, the region that binds the regulatory protein HDM-2, to a membrane-residency peptide sequence. The design is intended to exploit a feature reported in many cancer cell lines: elevated HDM-2 expression on the outer cell membrane, which is largely absent from normal cells.

This listing is PNC-27 (10 vials × 5mg) from TFC Peptides (Tianjin, China), sold on Stairway to Gray with escrow: your payment is held until the order arrives and only then released to the brand.

How it is understood to work

PNC-27 is reported to bind membrane-associated HDM-2 on cancer cells and, through its membrane-penetrating segment, form pores in the cell membrane that cause rapid cell lysis. Because this action is described as necrosis triggered at the membrane rather than classical apoptosis through intracellular p53 signaling, researchers study it as a mechanism distinct from typical p53-pathway reactivation strategies.

Research status

PNC-27 is studied almost exclusively in in-vitro oncology research, using cultured cancer cell lines to examine membrane-targeted cytotoxicity and selectivity relative to normal cells lacking membrane HDM-2. This work remains at the cell-culture stage; it has not been evaluated in controlled animal or human trials, so claims about anti-cancer efficacy are not established.

Lab testing

There is no public lab report for this listing yet. We can ask the brand for the batch COA before you order. Many buyers also split an independent HPLC test with others who bought the same batch.

Request the batch COA · How group testing works

Bought through escrow: the brand is only paid after you confirm delivery. If the parcel never arrives, or an independent test shows the wrong compound or a significant under-fill, open a claim before releasing payment.

Questions

How does PNC-27’s mechanism differ from other p53-related peptides?

Rather than restoring p53 activity inside the cell nucleus, PNC-27 is designed to act at the cell membrane, binding surface HDM-2 and physically disrupting the membrane, a distinct mode of action from intracellular p53-MDM2 pathway modulators.

Why is normal-cell selectivity reported for PNC-27?

Researchers report that normal cells largely lack membrane-surface HDM-2 expression, which is proposed as the basis for PNC-27’s selective activity in cancer cell models, though this selectivity has only been characterized in vitro.

How much PNC-27 is in this kit?

10 vials of 5mg each. The lab testing section above shows what the brand’s tested sample actually contained, where a report exists.
