The alpacas held at the Max Planck Institute for Biophysical Chemistry roam freely over large meadows. Following very mild immunizations of two alpacas, the Göttingen researchers retrieved construction plans for the secondary nanobodies from a small blood sample. Using these plans, bacteria can be programmed to produce them in large-scale without further animal involvement.
