| 摘要 |
The invention relates to a method allowing identification and/or quantifying and/or characterizing proteins in a protein mixture, wherein the proteins are stratified on feature(s) on an array, and a procedure, preferably mass spectrometric analysis, is applied on the proteins on the feature(s), allowing determination of the nature and quantities of the proteins. In particular, the method allows the comparative analysis of nature and amount of proteins in at least two samples. It also allows the targeted selection of proteins out of a mixture of proteins. It further identifies three-dimensional structures that can interact with a selected target protein or a modification of said protein. |
