Abstrakt: Despite substantial development of production and purification protocols for heterologous recombinant proteins, some proteins are difficult to produce or, when produced, are accumulated in inclusion bodies (IBs). Nondenaturing protocols can be used to recover the entrapped protein from these protein aggregates. In this chapter, we provide a detailed procedure to analyze the physicochemical properties of one of those proteins produced in prokaryotic expression systems. Serum amyloid A3 (SAA3) was recovered from inclusion bodies (IBs) and its secondary structure associated to thermal stability and size was determined by circular dichroism (CD) and dynamic light scattering (DLS), respectively. These techniques were also applied to evaluate the SAA3 interaction with model membranes. These results show the importance of the structural analysis of proteins released from inclusion bodies under nondenaturing procedures, although similar approaches can be extended to any type of recombinant protein preparation.
