PNC-27 10 mg from Peptide Tech is a chimeric, lyophilized research-use-only (RUO) peptide that fuses the p53 (residues 12–26) HDM2-binding motif to the cell-penetrating peptide penetratin. Each lot is supplied at ≥99% purity (HPLC & MS verified) with batch traceability for reproducible in-vitro mechanistic studies (membrane interaction, target engagement, pore-formation models) and peptide analytics.

Potential Applications in Research

Strictly for in-vitro, cell-based, or biochemical experiments. No health, diagnostic, or therapeutic claims.

HDM2 interaction & localization — co-IP, proximity assays, and membrane colocalization in lines reported to present membrane-associated HDM2.
Membrane pore-formation models — liposome leakage, GUV disruption, bilayer conductance to dissect peptide-induced membranolysis.
Cellular cytotoxicity profiling — LDH release, caspase readouts, and live-cell imaging to compare necrosis vs. apoptosis under controlled conditions.
Structure–function mapping — compare full chimera vs. segments (p53 motif alone, penetratin alone) and scrambled controls.
Target-dependency studies — correlate HDM2 presence/compartmentalization with in-vitro sensitivity.

Quality, Handling & Experimental Notes

Verification: Independent U.S. labs validate purity, identity, quantity, and endotoxin; COA linked via on-vial QR.
Reconstitution: Bring vial to RT; add sterile water (or ≤0.1% acetic acid for rapid wetting) then adjust into assay buffer. Avoid vigorous vortexing; use gentle swirl or brief sonication.
Aliquoting: Prepare single-use aliquots to minimize freeze–thaw; store frozen.
Controls: Include scrambled or segment-only controls (p53 motif alone, penetratin alone) for mechanistic interpretation.

Shipping & Fulfillment

Ships with validated cold-chain packaging. In-stock orders placed before the daily cutoff ship the same day. 2-Day FedEx/UPS is standard, with overnight options available. Automated text/email updates included; international shipping available where permitted.

Compliance & RUO Notice

For laboratory research only. Not a drug, cosmetic, food, or household chemical. Not for human or animal use, ingestion, diagnostic, or therapeutic applications. Not FDA-approved. Purchaser warrants appropriate qualifications and compliance with applicable regulations and institutional policies.

FAQs

Is this suitable for in-vivo use?: No. This product is supplied strictly as RUO and must not be administered to humans or animals.
How do I verify my vial?: Scan the on-vial QR code to access the batch COA with HPLC/MS data and third-party analytics.
Which buffer should I use?: Most groups start in sterile water, then adjust into isotonic buffers (e.g., PBS) at the target pH. Confirm compatibility with your assay and include appropriate controls.
