We do not ask you to trust a batch average. Each lot is independently tested and given a unique certificate of analysis you can match to the lot number printed on your vial.
From sequence to sealed vial
Solid-phase synthesis
Sequences are assembled by Fmoc solid-phase peptide synthesis, then cleaved and precipitated under controlled conditions.
Preparative HPLC
Crude peptide is purified by preparative reverse-phase HPLC and the target fraction is collected to ≥99% homogeneity.
Independent assay
Identity and purity are confirmed by analytical HPLC and mass spectrometry at third-party laboratories before release.
Built to a standard,
not a shortcut.
BioPura works from a certified, quality-assured facility, maintaining a full chain of custody from synthesis right through to dispatch.
Questions,
answered plainly.
All BioPura products are sold strictly for in vitro laboratory research and development. They are not medicinal products, supplements or medical devices, and are not intended for human or veterinary use, consumption or clinical application.
Each lot number matches a unique COA. The certificate lists the assay purity (by RP-HPLC), confirmed molecular identity (by mass spectrometry), net peptide content and the testing laboratory.
Lots are independently verified by accredited analytical laboratories. Results are published unedited on each product page, including the chromatogram and method parameters.
Lyophilised peptides are dispatched in insulated, ice-packed packaging within 24 hours. Store unreconstituted peptides at -20°C and reconstituted material at 2–8°C.
We release lots at ≥99% assay purity. The measured value is printed on the label and certificate; if a lot does not meet specifications, it is not released for sale.
