An essential part of artificial libraries is the production of semi‐synthetic libraries. The first semi‐synthetic collection was reported in 1992, in which reformation of 49 human VH gene sections with five to 8 residues of artificial CDR was performed to generate a semi‐synthetic single‐chain piece variable library. The crucial distinction in between semi as well as fully artificial collections is the resource of the variety. In semi‐synthetic libraries, the variety is mostly acquired from natural sources whereby the genes inscribing the CDR are separated. These CDR genetics are then inserted to a repaired structure sequence, which encodes the antibody foundation. The diversity is still natural, making the most of the maturation processes of antibodies in vivo. The application of artificial antibodies to establish antibodies for analysis applications has actually permitted the generation of antibodies versus numerous antigens of analysis worth.
