What is KLH?

Intricate KLH Molecule

Intricate KLH Molecule

Keyhole Limpet Hemocyanin (KLH) is an important immune-stimulating protein with an extensive history of safe and effective use in immunotherapy (therapeutic vaccine) development.

This versatile molecule can be combined with a disease-targeting agent to create a novel immunotherapy, or used alone to assess the body’s immune response.  But KLH can only be obtained from a scarce marine source, the Giant Keyhole Limpet.  Our ground-breaking achievements in aquaculture science and KLH production ensure that this critical natural resource thrives.

Our Success Starts with KLH

About Stellar

Stellar Biotechnologies, Inc. is the leader in sustainable manufacture of Keyhole Limpet Hemocyanin (KLH) protein. We are focused in the rapidly-evolving field of immunotherapy and we are positioning our business to lead in the long-term supply of KLH.

At Stellar, we did something no one else could.  We developed the proprietary ability to sustainably produce this essential molecule, and we set new benchmarks for its manufacture and the protection of its natural marine source.  We are committed to applying our Stellar KLH™ products to power and improve the drug therapies that treat disease by activating the body’s immune system.
