Horizontal two‐dimensional electrophoresis of cerebrospinal fluid proteins with immobilized pH gradients in the first dimension

A horizontal two‐dimensional electrophoresis method with immobilized pH gradient isoelectric focusing supplemented with carrier ampholytes in the first dimension was applied to cerebrospinal fluid (CSF) proteins. About 300 protein spots could be detected on the silver‐stained two‐dimensional maps of CSF samples. This highresolution method is a tool worthy of consideration for the research of CSF proteins and disease‐specific changes in different neurological disorders.
