High-Throughput Protein Production in Yeast.

Yeasts are versatile single-celled fungi that grow to high cell densities on inexpensive media. With well-studied genetics and metabolism and a wealth of knowledge available about their propagation and growth in academic as well as industrial settings, yeasts have long been used for recombinant protein production of isolated proteins and multisubunit complexes. They can be easily adapted to high-throughput protein expression pipelines. Importantly, the outcome from small-scale expression evaluations in high-throughput mode is scalable to laboratory and industrial scales using well-established procedures. In this chapter, we offer a state-of-the-art perspective on currently available high-throughput pipelines for protein production in S. cerevisiae and P. pastoris and discuss future challenges and avenues for improvement.
