Sarkosyl Preparation of Antigens from Bacterial Inclusion Bodies

Abstract

In many cases, solubility and proper folding of fusion proteins expressed in bacteria pose a major challenge in protein purification and crystallization. This is especially true when the fusion proteins are of eukaryotic origin. They form aggregates or become packaged into inclusion bodies, which makes protein purification extremely difficult. Sarkosyl is widely used to extract misfolded proteins from inclusion bodies in soluble form.
