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and/or purify proteins and/or studies that include extensive protein characterization, which provide new, previously unpublished information.

《蛋白質表達與純化》是一份國際期刊，為利用傳統生化和/或現代分子生物學方法和方法傳播蛋白質表達、提取、純化、表征和/或應用方面的新信息提供了一個論壇。該雜志通常不發表重復的蛋白質表達和純化的例子，涉及標準的，完善的，方法。然而，例外情況可能包括對重要和/或難以表達和/或純化蛋白質的研究，以及/或包括廣泛的蛋白質特性研究，這些研究提供了以前未發表的新信息。
