Cellugenix Peptides follows a structured production and testing process for every batch manufactured, from raw material sourcing through final Certificate of Analysis (COA) generation. All products are intended strictly for laboratory research use and are not approved for human or animal consumption, injection, or any clinical application. This page explains how peptides are synthesized, tested, and verified before they reach a researcher's bench.
Cellugenix peptides are produced using solid-phase peptide synthesis (SPPS), the standard method used across the research peptide industry for building peptide chains with precision. The process happens in a sequence of controlled steps:
Raw material sourcing – Amino acid building blocks and reagents are sourced from qualified suppliers and checked for identity before use.
Resin attachment – The first amino acid is attached to a solid resin support, which anchors the growing peptide chain during synthesis.
Sequential coupling – Amino acids are added one at a time in the correct order, following the target peptide sequence, with each addition monitored for completion before the next step begins.
Deprotection cycles – Protective chemical groups are removed between coupling steps so the next amino acid can attach at the right position.
Cleavage from resin – Once the full sequence is built, the completed peptide chain is cleaved from the solid resin support.
Purification – The raw peptide is purified using preparative HPLC to separate the target peptide from any incomplete sequences or byproducts formed during synthesis.
Lyophilization – The purified peptide is freeze-dried into a stable powder form for shipping and storage.
Every batch produced by Cellugenix goes through a defined testing sequence before it is approved for sale. Testing is handled by Testides, an independent third-party laboratory, so results are not generated in-house.
| Test | Purpose | Method Used |
|---|---|---|
| Purity analysis | Confirms the percentage of target peptide in the sample | Reversed-phase HPLC (High-Performance Liquid Chromatography) |
| Identity confirmation | Confirms the molecular structure matches the intended peptide | Mass spectrometry (MS), comparing observed mass to theoretical mass |
| Endotoxin testing | Checks for bacterial contamination byproducts | Endotoxin quantification assay |
| Residual solvent testing | Checks for leftover solvents from the synthesis process | Solvent analysis |
| Appearance and solubility check | Confirms physical characteristics match expected standards | Visual inspection and solubility testing |
Every batch shipped by Cellugenix is accompanied by a COA generated by Testides. Each COA includes the following information:
Updated COAs for current batches can be viewed directly on the Cellugenix website. Researchers are encouraged to match the lot number on their vial with the lot number listed on the corresponding COA before beginning any work with the sample.
Cellugenix sets a minimum purity threshold for every peptide it sells, and batches that fall below this threshold are not released for sale.
| Purity Grade | Minimum HPLC Purity | Typical Use Case |
|---|---|---|
| Standard research grade | 98% | General laboratory research |
| High-purity grade | 99%+ | Studies requiring tighter analytical precision |
We prioritize transparency and traceability for every product we manufacture. This section details how we track, archive, and manage batch data to ensure reliable results for your research.
