Abstract

The potential of recombinant antibody fragments is likely to be fulfilled only if they can be produced routinely at high concentrations. We have compared the ability of Escherichia coli and Pichia pastoris to produce functional recombinant single chain antibody (scAb) fragments. Two scAb fragments were expressed, an antihuman type V acid phosphatase (TRAP) and an anti-Pseudomonas aeruginosa lipoprotein I. We report here that, while expression from P. pastoris resulted in a significantly increased level of expression of the anti-TRAP scAb compared to E. coli, neither fragment was able to bind its target antigen as well as the bacterial product.
