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 ...
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.

Recombinant antibodies are monoclonal antibodies generated in vitro using synthetic genes. Recombinant antibody technology involves recovering the antibody genes from the source cells, amplifying and cloning the genes into an appropriate vector, introducing the vector into a host, and achieving expression of adequate amounts of functional antibody.
Antibodies are produced by B cells in two ways: (i) randomly, and (ii) in response to a foreign protein or substance within the body. Initially, one B cell produces one specific kind of antibody. In either case, the B cell is allowed to proliferate or is killed off through a process called clonal deletion. Normally, the immune system is able to ...
This staining pattern is seen with anti-Ro and anti-La antibodies. Anti-Ro and anti-La antibodies, also known as SS-A and SS-B, respectively, are commonly found in primary Sjögren's syndrome, an autoimmune disorder that affects the exocrine glands. The presence of both antibodies is found in 30–60% of Sjögren's syndrome, anti-Ro antibodies ...
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.
Proteins of the IgSF possess a structural domain known as an immunoglobulin (Ig) domain.Ig domains are named after the immunoglobulin molecules. They contain about 70-110 amino acids and are categorized according to their size and function. [2]
A plantibody is an antibody that is produced by plants that have been genetically engineered with animal DNA encoding a specific human antibody known to neutralize a particular pathogen or toxin. The transgenic plants produce antibodies that are similar to their human counterparts, and following purification, plantibodies can be administered ...
