With one of the most unique immune systems, many researchers are hoping Llamas will be key to finding cures to our most common threatening diseases. Llamas have unique heavy chain only antibodies that bind to epitopes and are inaccessible to traditional antibodies. They have a longer shelf-life, higher tolerance to extreme conditions, and a higher pH. Recombinant “nanobodies”, or antigen-binding single domain proteins are easily engineered from llama antibody genes.
