Potential Applications in Research (RUO)

Strictly for laboratory research. No health, diagnostic, or therapeutic claims.

Airway epithelium models — quantify epithelial wound-closure, barrier recovery (TEER), and mucin gene panels (e.g., MUC5AC) under controlled EDP exposures; include vehicle and positive controls.
Fibroblast signaling & ECM readouts — measure collagen I/III, elastin, and cytokines via RT-qPCR/ELISA in lung-fibroblast cultures challenged with defined stimuli.
Oxidative-stress assays — evaluate ROS, antioxidant enzyme transcripts, and mitochondrial potential in airway or epithelial cell lines across media compositions.
Peptide-transport profiling — explore uptake and stability of small acidic tripeptides in Caco-2/HEK models expressing PEPT systems; pair with LC–MS quantitation.
Analytical method development — establish RP-HPLC/LC–MS(/MS) for identity, purity, recovery, and forced-degradation stability across buffers and temperatures.

Quality, Storage & Handling

Every lot is confirmed by HPLC (purity) and MS (identity); the on-vial QR links to the batch COA. Independent U.S. labs verify purity, quantity, and endotoxin.

Storage (lyophilized): −20 °C long-term or 2–8 °C short-term; keep desiccated and protected from light.
After reconstitution: Aliquot and store at ≤ −20 °C (or −80 °C per SOP); avoid repeated freeze–thaw cycles.
Reconstitution tips: Use sterile water or suitable buffer; gently swirl/invert to dissolve. If sterility is required, 0.22 µm filter and aliquot promptly.

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 Disclaimer

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

FAQs

Is Chonluten the same as Vesugen or Vilon?: No. Chonluten is the tripeptide Glu–Asp–Pro (EDP). Vesugen is Lys–Glu–Asp (KED), and Vilon is Lys–Glu (KE). Confirm the sequence required by your assay.
Do you provide a PubChem image?: Yes—the 2D structure above is rendered from PubChem CID 14023897 for EDP (Glu–Asp–Pro).
What purity do you provide?: Each 20 mg vial is ≥99% by HPLC with MS identity confirmation; third-party testing is performed on every lot (COA via on-vial QR).
How should I reconstitute it?: Dissolve in sterile water or a compatible buffer; gently invert until fully dissolved. If your SOP requires sterility, 0.22 µm filter and aliquot to avoid repeat freeze–thaw.
