New antibody derivatives are continuously being generated to interact with a range of therapeutic targets. The cost-effective and efficient production of these and other antibody derivatives is crucial for their further success. Here, we describe the construction of the expression vectors needed for heterologous expression of a Fab fragment in the yeast Pichia pastoris . The experimental conditions for lab-scale expressions are discussed, and an overview of an efficient purification strategy is presented.
