Immune complexes in blood: a new strategy for the analysis of their antigen portion

Application of two-dimensional protein gels in biotechnology

The optimal use of biological systems for technologically developed products will not be achieved until biological systems are completely defined in biochemical terms. Two-dimensional polyacrylamide gel electrophoresis, 2-D gels, are contributing to this goal. These gels separate complex mixtures of proteins into individual polypeptide species. The ultimate use of 2-D gels is the construction of cellular 2-D gel databases which identify the proteins on the gels and catalog their responses to different environmental conditions. In addition to these global analyses, many applications for 2-D gels in basic, applied and clinical research have been shown.
