A system for functional analysis of complementary DNA (cDNA)-encoded proteins was described in which selected portions of cDNAs are expressed as part of a fusion protein used for immunization to elicit antibodies. The concept of antibody-based proteomics was further developed and used in the HPA effort to generate more than 55,000 human recombinant proteins and 55,000 antibodies.
