  We summarize recent work on low-x deep inelastic scattering. The generalized
vector dominance/color-dipole picture (GVD/CDP) implies a scaling behavior for
$\sigma_{\gamma^* p} (W^2, Q^2)\cong \sigma_{\gamma^* p}(\eta)$, with $\eta =
(Q^2 + m^2_0)/\Lambda^2 (W^2)$ and yields an excellent representation of the
experimental results on $\sigma_{\gamma^* p}(\eta)$.
