Keyhole limpet hemocyanin (KLH) is a potent immunostimulating protein with an extensive history of safe and effective use in vaccine development and immunological research. 

This vitally important protein can only be derived from a limited natural resource – the giant keyhole limpet (Megathura crenulata) which naturally lives and grows only in the Pacific waters off portions of California and Baja, Mexico.

Already widely used in immunology-related research applications, the use of KLH as an essential component of conjugate vaccines and a useful tool in clinical research is growing rapidly.

Stellar Biotechnologies specializes in ensuring renewable, environmentally-sound supply of quality KLH products.
