| pubmed-article:18429284 | pubmed:abstractText | With the introduction of DNA microarrays as novel analytical tools, the determination of thousands of binding events in one reaction became possible. The developed technology platforms are not limited to nucleic acids, and, in principle, every ligand-binding assay that works on solid phase can be miniaturized and brought into an array format. This unit explains how protein microarrays can be generated using equipment originally designed for DNA microarrays and how multiplexed assays for the quantification of proteins are set up. A protocol that describes a parallelized system for detecting autoantibodies in human serum is included as an example, and it is shown how existing sandwich immunoassays can be miniaturized and performed in array format. The unit also provides some theoretical background and commentary on the problems associated with this still-novel technology. | lld:pubmed |
