The recombinant antibodies may also be used in fused form with drugs and/or toxins, which may be further exploited in the medical applications. Last but not least of their advantages during production is the possibility to optimize and genetically engineer the recombinant antibodies based on the current demand of the patient or researcher.

Antibody (or immunoglobulin) structure is made up of two heavy-chains and two light-chains. These chains are held together by disulfide bonds. The arrangement or processes that put together different parts of this antibody molecule play important role in antibody diversity and production of different subclasses or classes of antibodies.
The framework regions are highly conserved regions of the variable portion of the antibody. The evolutionary reason for the conservation of these regions is to support proper folding of the antibody allowing the CDR regions to be stabilized. Folding in FR leads to antibody structure flexibility or rigidity of the binding region of the antibody ...
Recombinant antibodies can be cloned from any species of antibody-producing animal, if the appropriate oligonucleotide primers or hybridization probes are available. [4] The ability to manipulate the antibody genes make it possible to generate new antibodies and antibody fragments, such as Fab fragments and scFv in vitro. This can be done at ...
Ig-domains possess a characteristic Ig-fold, which has a sandwich-like structure formed by two sheets of antiparallel beta strands. Interactions between hydrophobic amino acids on the inner side of the sandwich and highly conserved disulfide bonds formed between cysteine residues in the B and F strands, stabilize the Ig-fold.
Each antibody binds to a specific antigen in a highly specific interaction analogous to a lock and key.. An antibody (Ab) or immunoglobulin (Ig) is a large, Y-shaped protein belonging to the immunoglobulin superfamily which is used by the immune system to identify and neutralize antigens such as bacteria and viruses, including those that cause disease.
In the vertebrate immune system, each antibody is customized to attack one particular antigen (foreign proteins and carbohydrates) without attacking the body itself. The human genome has at most 30,000 genes, and yet it generates millions of different antibodies, which allows it to be able to respond to invasion from millions of different antigens.
Immunofluorescence pattern of SS-A and SS-B antibodies. Produced using serum from a patient on HEp-20-10 cells with a FITC conjugate. Anti-SSA autoantibodies (anti–Sjögren's-syndrome-related antigen A autoantibodies, also called anti-Ro, or similar names including anti-SSA/Ro, anti-Ro/SSA, anti–SS-A/Ro, and anti-Ro/SS-A) are a type of anti-nuclear autoantibodies that are associated with ...
