With DLS you can measure the hydrodynamic radius (Rh) of your protein
which will depend on many things such as viscosity of the medium, shape
of the molecule, etc. Stokes-Einstein law is used for the estimation of Rh.
Normally the maschine parameters are set for a fairly globular ("round")
and
Kindly answer this
How to calculate the molecular weight of protein samples using DLS analysis
Size distribution by intensity
The purified protein was subjected to DLS - scattering light intensity
analysis (Horiba nanoparticle analyzer sz-100) and the Z average result was
71.6nm. from this result
