  Welcome to Ludger

The team of specialists at Ludger can provide glycoprofiling services and technology to help you engineer, optimise, measure and control the glycosylation of your therapeutic glycoprotein product. It can be used within a QbD framework for biopharmaceutical realisation. Established in 1999 we have a wealth of experience providing structural glycan characterisation of innovator and biosimilar biotherapeutics, including:

  • Monoclonal antibodies (mAbs)
  • Hormones e.g erythropoeitin (EPO)
  • Fc fusion proteins
  • Plant glycoproteins
  • Viral glycoproteins
  • Parasitic glycoproteins
  • Vaccines
  • Clotting factors

This will help you address safety, efficacy, product consistency, stability and half-life, regulatory compliance, patent issues and comparability of your drugs. Analytical methods used in house include (U)HPLC, ESI-MS, MALDI-MS, LC-MS. In addition we can work to Good Manufacturing Practice (GMP) level services for our clients.

  Quality and Reliability

Ludger operates a Quality Management System (QMS) which covers all aspects of the company's operations, including glycoprofiling contract analysis, and is based on the ISO 9001:2008 registration framework. Ludger is an ISO9001 Registered Company.
