We supply pharmaceutical and research markets with a range of quality Stellar KLH™ products and services. Stellar Biotechnologies' controlled, land-based aquaculture provides high yields of clean, pure, and traceable KLH. Our extraction and refinement methods ensure vitality of protein source, quality control, reproducibility and protein stability. This is Stellar KLH™.
Stellar KLH™ protein for vaccine conjugation, immunotoxicology, and immunological research.
Formulations:
To ensure optimum immunogenic potency of the native molecule, Stellar KLH™ is produced directly from our own quality controlled source colonies, always freshly processed, and purified in liquid form either as stable high molecular weight KLH complex or the constituent stable KLH subunit.
Stellar KLH™ is always in liquid form, never lyophilized. Lyophilization (freeze drying) is known to induce structural changes in proteins, including possible denaturation and dissociation of molecular complexes. Stellar KLH™ is rigorously evaluated for the absence of endotoxin and microbial pathogens.
- Stellar KLH™ HMW - High molecular weight (4 – 8MDa) stable preparation in DPBS buffer. Liquid form. Known for high purity (>98%) and immunogenicity. Used in conjugate vaccines and as a neoantigen for immune stimulation.
- Stellar KLH SUBUNIT - Stable preparations of KLH subunits (+600 - 800 KDa) in water for injection (WFI). Ready for conjugation to vaccine antigens. Highly purified (>95%) with homogeneous size distribution.
- Stellar KLH ASP - High molecular weight native KLH formulations in ammonium sulfate (ASP) slurry. Purity >87%. Uses including as starting material for GMP manufacturing of both subunit and high molecular weight KLH forms.
Grades & Quality:
Our commitment to quality is built into every step of the manufacturing process; from aquaculture cultivation, through protein purification and processing, to final product form.
To satisfy the exacting requirements of our vaccine customers, Stellar Biotechnologies offers KLH products manufactured to Good Manufacturing Practice (GMP) standards and quality control. We also offer research grade (non-GMP) product in bulk preparations for use in research settings.
Stellar Biotechnologies' patented extraction, clean collection, and proprietary refinement methods ensure that Stellar KLH™ material has consistently low endotoxin, viral and bioburden levels.

New Stellar development!
Stellar Biotechnologies is currently developing a range of products for use in immunotoxicology, immunochemistry and immunology applications where KLH is used to assess cellular and/or humoral immune responses.
Our goal is to apply Stellar KLH™ protein and standards to develop a deep product line of injectables, ELISA assays, and DTH tests which will help pharmaceutical developers and clinicians to improve the predictive value of drug toxicology and assessment of immune competence.
