Four peptides. Four fields of research.

A tissue peptide from gastric juice, a copper complex from plasma, a messenger from the mitochondrial genome and a tetrapeptide from pineal gland research. What they share: an unusually active research literature.

All peptides
  1. 01BPC-157Stable gastric pentadecapeptideA 15-amino-acid fragment of a gastric juice protein that has been studied unusually broadly in animal models. One of the most discussed research peptides, with an evidence base that is almost entirely preclinical.PreclinicalClinicalRUO10 mg lyophilisate
  2. 02GHK-CuCopper tripeptide from human plasmaA naturally occurring tripeptide that binds copper(II) and whose plasma concentration declines with age. Studied in cell culture and animal models since the 1970s, particularly well documented in skin research.PreclinicalClinicalRUO100 mg lyophilisate
  3. 03MOTS-cMitochondrially encoded peptideA 16 amino acid peptide whose blueprint lies not in the cell nucleus but in the mitochondria's own genome. Since its discovery in 2015, a model for the question of how mitochondria help steer the metabolism of the whole cell.PreclinicalClinicalRUO10 mg lyophilisate
  4. 04EpitalonTetrapeptide from pineal gland researchFour amino acids, designed after a peptide extract of the pineal gland. Known for findings on telomerase in cell culture and for long-term studies in mice; the literature still comes predominantly from one research group in Saint Petersburg.PreclinicalClinicalRUO10 mg lyophilisate

All four as lyophilisate, for research use only.

From the lab

What we measure, we show.

Six stations between goods receipt and release. Every batch passes through them in the same order.

Methodology in detail
Rows of HPLC vials with blue caps in an autosampler
01SamplingVials in the autosampler, every sample assigned to one batch.
Analytical balance with weighing boat and spatula
02WeighingAnalytical balance, weighed to 0.01 mg.
Volumetric flasks and beakers with clear liquid, backlit
03SolutionClear and colourless. Otherwise the batch is blocked.
Rack of cryo vials above liquid nitrogen
04Retained sampleA sample of every batch is kept deep-frozen.
Gloved hand placing a sample tube into a centrifuge
05PreparationCentrifugation before injection into the HPLC.
Vials with freeze-dried peptide in a freeze dryer
06LyophilisateFreeze-dried, kept refrigerated and protected from light until dispatch.
PURA LABS drawer box, open, with two cartons for peptide and bacteriostatic water
Two glass vials with PURA LABS labels: peptide with a green cap, bacteriostatic water with a blue cap
The product

One vial, one batch, one report.

Each peptide comes as a lyophilisate in a glass vial, in its own carton, together with bacteriostatic water in the drawer box. Every label carries the lot number that leads to the test report.

  • Lyophilisate in a vial. Freeze-dried, sealed, to be stored refrigerated. Amount and CAS number are printed on the label.
  • Two cartons, one box. Peptide and bacteriostatic water sit in separate cartons. No syringes, no accessories for use.
  • Lot number and QR code. Both lead to the batch report: chromatogram, mass spectrum, specification, testing laboratory.

Methodology

How we test every batch.

From goods receipt to publication every batch follows the same procedure. The specification is fixed before anything is measured.

  1. 01Sampling and hand-over to an accredited, independent laboratory
  2. 02Identity by ESI-MS, purity by RP-HPLC at 220 nm
  3. 03Water content, acetate content and peptide content
  4. 04Release only if every value lies within the specification

About PURA LABS

Knowledge instead of promises.

PURA LABS is a young company with a simple idea: research needs substances that are well described and verifiable. Not advertised, but classified, measured and published.

PURA LABS supplies research peptides with a profile, a classified evidence overview and complete analytics. For research use only, not for human or animal use. More on labelling
