A method for specifically immunoprecipitating albumin from a serum sample, using a "collapsible affinity matrix". Also provided is a method for the co-removal of immunoglobulin using a "collapsible affinity matrix". Removal of the highly abundant serum proteins, albumin and immunoglobulin, thereby improves the fractionation of the remaining serum proteins. Due to the collapsible nature of the matrix, less protein is trapped in the void space. Through specific removal of the abundant serum proteins by the collapsible affinity matrix and application of a two-dimensional gel electrophoresis method, HiCap 2-D PAGE, the concentrations of a large number of low abundant serum proteins are estimated simultaneously, allowing the identification of several disease-related proteins in a relatively short period of time. |
