Aims & Scope
Protein Expression and Purification is an international journal providing a forum for the dissemination of new information on protein expression, extraction, purification, characterization, and/or applications using conventional biochemical and/or modern molecular biological approaches and methods, which are of broad interest to the field. The journal does not typically publish repetitive examples of protein expression and purification involving standard, well-established, methods. However, exceptions might include studies on important and/or difficult to express and/or purify proteins and/or studies that include extensive protein characterization, which provide new, previously unpublished information.
