Products
GMP Grade
Stellar's GMP-grade KLH products are made exclusively from our colony of aquacultured Megathura crenulata using the highest standards of biopharmaceutical processing and quality control.
The KLH protein is a flexible and proven carrier platform for conjugate vaccines in humans. The molecule's potent T-cell dependent antigen presentation properties are matched by compelling safety features, including a lack of toxicity and the absence of TSE (transmissible spongiform encephalopathy) risk.
Environmentally Sound
Stellar's proprietary KLH production processes begin with a patented, non-lethal extraction method for the collection of hemolymph from giant keyhole limpets.
Low Endotoxin
The use of sterile extraction and "clean catch" collection methods result in KLH products with the lowest possible endotoxin and bioburden levels - a significant advantage for immunological testing and vaccine formulation.
Sustainable Supplies
Stellar's sustainable production methods allow hemolymph to be repeatedly harvested from the animals in our aquaculture production colony and minimizes the use of the limited natural population of animals available from the ocean.

Quality Commitment
Stellar’s GMP-grade KLH products are setting new standards for quality and traceability, and are routinely used in the manufacture of clinical trial vaccines and immunotherapies for cancer and other chronic diseases. Our commitment to quality is built into every step of the manufacturing process, from animal husbandry to protein purification to Quality Assurance.
All of Stellar's KLH products are available from aquaculture animals. These KLH products can also be produced from non-aquaculture (ocean-harvested) animals as special-order items. Please inquire for pricing and availability.
