Antibody Arrays :
Antibody microarrays are glass slides or other chip types with antibodies attached to their surface. These antibodies are usually monoclonal antibodies specific against proteins of interest. The newer antibody microarrays can have over 500 antibodies arrays on their surface. Instead of conducting many western blot analyses, one can simply use an antibody microarray to profile changes in protein expression levels.
