2.7. Dynamic light scattering (DLS) analysis
The structural integrity of the purified virus particle, along with TEM analysis can be determined by the size distribution profile through dynamic light scattering (DLS) approach. The DLS studies were performed on Nanophox (Sympatec GmbH, Claushtal, Germany) in a buffer containing 20 mM Tris-HCl, pH 7.3 at the room temperature.
