Abstract：
The analytic expression of proton in deep inelastic scattering is studied by using the color glass condensate model and the dipole picture. We get a better description of the HERA DIS data than the GBW model which was inspired by the Glauber model. We find that our model satisfies the unitarity limit and Froissart
Bound which refers to an energy dependence of the total cross-section rising no more rapidly than ln² s.
