Figure 3

Comparison of direct and prefractionated CSF on SYPRO Ruby stained 2-D gels. The upper figures represents standard images of direct 2-DE, and the lower figures represents prefractionated 2-DE. The pH interval of the IPG strips is denoted in the upper left corner of the gels and the pH range of the prefractionated CSF samples at the bottom of the gel images. Molecular weights (MW) are in kDa.
