For a light field, the wavefront determines the axial variation of the intensity in the direction of propagation. Specifically, there is a quantitative relationship between the gradient and curvature of the phase and the axial differentiation of intensity, the so-called transport of intensity equation...
After desalting, the peak fractions were loaded onto a HiTrap Q column (GE Healthcare) and washed sequentially with lysis buffer at different salt concentrations (50 mM KCl; 87.5 mM KCl; 200 mM KCl), before final fractions were eluted in lysis buffer using a salt gradient from 200...
