Efficient full-length IgG secretion and sorting from single yeast clones in droplet picoreactors.

The search for new antibodies is a major field of pharmaceutical research that remains lengthy and costly due to the need for successive library screenings. Existing and antibody discovery processes require that libraries are repeatedly subcloned to switch the antibody format or the secretory host, a resource-intensive process. There is an urgent need for an antibody identification platform capable of screening large antibody libraries in their final soluble format.

Bidirectional hybrid erythritol-inducible promoter for synthetic biology in Yarrowia lipolytica.

Background: The oleaginous yeast Yarrowia lipolytica is increasingly used as a chassis strain for generating bioproducts. Several hybrid promoters with different strengths have been developed by combining multiple copies of an upstream activating sequence (UAS) associated with a TATA box and a core promoter. These promoters display either constitutive, phase-dependent, or inducible strong expression.
