Stellar Biotechnologies is a world leader in the development and production of keyhole limpet hemocyanin (KLH), a critical component of many conjugate vaccines and a highly regarded antigen in immunotoxicology and immunology.
We manufacture, directly from clean and sustainable aquaculture, pure Stellar KLH™ known for its high immunogenicity, purity and quality. Our customers include therapeutic vaccine companies using KLH as a carrier molecule, and medical researchers and clinicians using KLH-based methods in drug screening and assessment of immune status.
We ensure controlled, traceable and renewable supply of the highest quality KLH protein, and we provide services related to our deep knowledge base of KLH biochemistry and immunology.
We are leading new development of a range of Stellar KLH™ diagnostic products and assays. Our goal is to improve the predictive value of drug immunotoxicology and offer standardized KLH-based tools for immunological testing.
Our exclusive systems include controlled aquaculture, patented protein extraction, novel processing and purification (patents pending), scalable capacity and unsurpassed environmental responsibility.
