Stellar KLH™ Protein for Vaccine Conjugation

Steller Protein

KLH is used extensively as a carrier protein in research and therapeutic vaccine applications.  Peptides, small proteins and drug molecules of low molecular weight are not usually immunogenic.  They require the aid of a carrier protein to stimulate antibody production.  KLH is a very effective and popular carrier protein due to its large size, numerous epitopes, plentiful sites for antigen conjugation, and strong safety history.

To satisfy the exacting requirements of our vaccine customers, Stellar offers KLH manufactured according to current Good Manufacturing Practices (cGMP). We also offer research grade (non-GMP) product in for use in research settings.

Advantages of Stellar KLH™ as a Carrier

The quality of KLH can effect conjugation and immune response.  Only Stellar KLH™ protein is produced from controlled, land-based aquaculture colonies of Megathura crenulata using Stellar Biotechnologies’ unmatched manufacturing processes and quality systems.  We ensure quality, consistent KLH with optimum immunogenicity for both your clinical and research needs.

  • Optimal immunogenicity
  • Pure, high quality KLH
  • Fully traceable back to source
  • Long-term, scalable supply for commercial use
  • Always in liquid form (never lyophilized which can diminish performance)
  • Produced using environmentally sound, sustainable methods

Stellar has long been the only company capable of producing sustainable supplies of KLH protein that are fully traceable and controlled, key criteria for our pharmaceutical partners.

Over the years, we have pioneered numerous milestones in KLH manufacturing, quality and sustainability.  Other KLH suppliers continue to rely on the small and sensitive, wild populations of the Giant Keyhole Limpet and cannot offer KLH that meets Stellar Biotechnologies’ standards.
