Recombinant protein quality: approaches for the quantitative evaluation of functional and structural features of purified proteins and antibodies

Edited by Prof Ario de Marco

Microbial Cell Factories welcomes submissions to this thematic series, covering all aspects of methodologies aimed at analyzing the preservation of the structure, solubility, and functionality of purified proteins and antibodies. Applications of new biophysical and imaging technologies are welcome, as well as the description of automated approaches. See here for further information, including how to submit.

This collection of articles has not been sponsored and articles have undergone the journal’s standard peer-review process. The Guest Editors declare no competing interests.
