About Us

Who We Are

LimeRiver Biotechnologies INC is a fully integrated biosciences company dedicated to the discovery and development of therapeutic antibodies derived from natural human immunity.

Our True Human™ antibody candidates are actually derived from donors with natural human immunity. No other marketed antibody product — including "humanized" and so-called "fully human" — are actually derived from natural human immunity.

Founded on the principle that nature holds the key to the most effective treatments, LimeRiver combines cutting-edge biotechnology with the power of natural immunity to develop breakthrough therapies for some of the world's most challenging diseases.

Our state-of-the-art facilities and world-class team of scientists are dedicated to advancing our pipeline of True Human antibodies through clinical development, with programs spanning oncology, neurology, rheumatology, and infectious diseases.
