Decades, Hundreds, Thousands


Keyhole Limpet Hemocyanin (KLH) is a vitally important protein molecule with an extensive history of use (50+ years) in therapeutic vaccine development and immunological research. It is widely used both as an active pharmaceutical ingredient (API) in certain immunotherapies and as a finished product for testing immune status in patients and research settings.

As an API, KLH is an effective carrier molecule in immunotherapies being developed for the treatment of various cancers and for other serious diseases such as Alzheimer's, lupus, dermatomyositis, and diabetes. KLH is also extensively used by pharmaceutical companies and researchers as a safe immune-stimulating antigen in drug immunotoxicology studies and for assessment of immune status. For example, KLH is a standard immunogen in T-cell Dependent Antibody Response (TDAR), a functional assay often used to monitor the effects of new drugs on the immune system.
