SAXS investigations of Lysozyme solutions were performed enabling the calculation of the radius of gyration (Rg) and of the Pair-distance Distribution Function (PDDF).

Introduction

The Small Angle X-ray Scattering (SAXS) technique is now well known for studying biological systems and more specifically protein solutions. SAXS measurements allow the determination of the macromolecular shape conformation i.e. by an envelope reconstruction of the investigated protein.
SAXS data were collected for the standard protein Lysozyme and enable the definition of both the Rg and the PDDF.
