title: Towards a two-dimensional database of common human proteins.
abstract: A protein pattern of common human proteins was constructed by comparing the two-dimensional gel electrophoresis (2-DE) protein patterns from five cell lines of different germ layers. Total cell lysate and the isolated and purified nuclei of each cell line were separated by parallel electrophoresis runs in a multiple casting system of highest reproducibility. The computerized image analysis of the digitized 2-DE gels revealed a master protein pattern for each cell line. By comparison of all master protein patterns a 2-DE protein map of only common human proteins was constructed as a basis for a new 2-DE database. In a first step we have started characterizing a number of spots by microsequencing, amino acid composition analysis, and mass spectroscopy.
