Heterologous expression of high amounts of recombinant proteins is a milestone for research and industrial purposes.

Abstract

Heterologous expression of high amounts of recombinant proteins is a milestone for research and industrial purposes. Single domain antibodies (sdAbs) are heavy-chain only antibody fragments with applications in the biotechnological, medical and industrial fields. The simple nature and small size of sdAbs allows for efficient expression of the soluble molecule in different hosts. However, in some cases, it results in low functional protein yield. To overcome this limitation, expression of a 6xHistag sdAb was attempted in different conditions in Escherichia coli BL21(DE3) cells. Data showed that high amount of sdAb can be expressed in E. coli classical inclusion bodies, efficiently extracted by urea in a short-time, and properly purified by metal ion affinity chromatography. These data originate from the research article "Enhanced expression and purification of camelid single domain VHH antibodies from classical inclusion bodies" Maggi and Scotti (2017)
