Custom Peptide Synthesis

TAG Copenhagen A/S is offering custom made peptides at the lowest prices in Europe

Throughout the years the peptides have been offered together with the TAG Copenhagen sister company KJ Ross-Petersen ApS. Over the past 10 years TAG Copenhagen and KJ Ross-Petersen have delivered more than 4000 different peptides to pharmaceutical companies, universities and institutions in Scandinavia, UK, Germany and France. TAG Copenhagen has carefully selected the ISO 9001:2000 certified collaborator performing the synthesis of the peptides – a company with many years of experience with organic chemistry and currently employs >250 chemist in the Production, QC/QA and R&D departments.

The peptides from our collaborator’s labs are synthesized on state-of-the-art instruments and the >250 staff consists of experienced organic chemists. Every peptide is delivered lyophilized with an analytical certificate with the amino acid- and HPLC analysis. Copies of the MassSpectra are available on request.

It has provided our customers with great confidence in the products - resulting in establishment of many long terms supply agreements. The manufacturer is consistently upgrading every aspect of their quality systems in terms of staff training, documentation and analytical capabilities so as to achieve highest quality standards. Every product we ship includes a Certificate of Analysis with complete detailed information on lot number, product information, date of manufacturing, date of expiry, specification and typical analysis data. The following procedures are applied in their quality systems to monitor the quality of products throughout the whole manufacturing process and even up to inventory:

  • Raw Material Quality Inspection (RMQ)
  • In-Process Quality Inspection (IPQ)
  • Final Product Quality Inspection (FPQ)
  • Certificate of Analysis (CoA) for our every lot of products
  • Maintain retained samples for each lot for at least one year
  • Shelf-life analysis data

List of Analytical Techniques used in the Inspection of Products include:  

  • Chromatography (HPLC, TLC, GC, IC)
  • Chromatography coupled to MS (LC-MS/ESI)
  • Spectroscopy (UV-Vis, IR, NMR)
  • Refractometry
  • Polarimetry
  • Metallic Analysis (AAS, ICP, ICP-MS)
  • Elemental Analysis
  • Titration (Acid-Base Titration, Karl Fischer Titration)
  • Amino acid analysis
