Testing out combinations of antiviral proteins from llamas could help researchers create potent virus-neutralizing multimers.

At an archaeological site in Peru, researchers have found the remains of hundreds of children and llamas sacrificed in the 15th century.

With multiple applications in biomedicine, the antibodies can now be made quickly, cheaply, and without the need for an alpaca or one of its relatives.

From diagnostics to vaccines, llama antibodies point to new directions in HIV research.
