Human liver protein map: a reference database established by microsequencing and gel comparison.

This publication establishes a reference human liver protein map obtained with immobilized pH gradients. By microsequencing, 57 spots or 42 polypeptide chains were identified. By protein map comparison and matching (liver, red blood cell and plasma sample maps), 8 additional proteins were identified. The new polypeptides and previously known proteins are listed in a table and/or labeled on the protein map, thus providing a human liver two-dimensional gel database. This reference map can be used to identify protein spots on other samples such as rectal cancer biopsies.

Plasma protein map: an update by microsequencing.

The reference plasma protein map, obtained with immobilized pH gradients in the first dimension of two-dimensional electrophoresis, is presented. By microsequencing, more than 40 polypeptide chains were identified. The new polypeptides and previously known proteins are listed in a table and labeled on the protein map, thus providing an update of the human plasma two-dimensional gel database.

Improving the detection of proteins after transfer to polyvinylidene difluoride membranes.

N-Terminal sequence analysis of proteins separated by two-dimensional polyacrylamide gel electrophoresis and transferred onto polyvinylidene difluoride (PVDF) membranes has become the method for molecular characterization of proteins contained in biological samples. However, the proteins of lower abundance cannot be sequenced directly, without improving the technique. We have studied a drying method on several PVDF membranes including Trans-Blott, Immobilon P and Problott. Using Amido Black, Coomassie Brilliant Blue R-250 and Ponceau S, we have obtained, in comparison with the non-dried membranes, an enormous increase in the number of detectable proteins.
