Overview
AbCelex Technologies develops camelid antibody platforms and therapeutic candidates for infectious diseases and other indications. Its engineered antibodies can be designed for oral delivery, longer half-life, better proteolytic stability, and tunable target binding, and the platform lets rapid creation of multi-specific and multivalent agents by swapping subunits. It has tested over 50 protein antigens and built more than 10 large libraries from immune and naïve origins, differentiating itself by the ability to rationally design and optimize discovery and therapy candidates. The goal is to move these antibody technologies toward clinical development and broaden their use in targeted, stable, and combinable therapeutics.
