Antibody opsonization is the process by which a pathogen is marked for ingestion and destruction by a phagocyte . Opsonization involves the binding of an opsonin , e.g., antibody , to a receptor on the pathogen s cell membrane. ref http cancerweb.ncl.ac.uk cgi bin omd?query opsonisation Definition opsonization from Online Medical Dictionary Bot generated title ref After opsonin binds to the membrane, phagocytes are attracted to the pathogen. The Fab portion of the antibody binds to the antigen, whereas the Fc portion of the antibody binds to an Fc receptor on the phagocyte, facilitating phagocytosis. ref Parham, P. 2005 . The Immune System, Garland Science Publishing, New York, NY. ref The receptor opsonin complex can also create byproducts like C3b and C4b which are important components of the complement system . These components are deposited on the cell surface of the pathogen and aid in its destruction. ref Kumar, V., Abbas, A. K., & Fausto, N. 2005 . Pathologic basis of disease. Philadelphia Elsevier Saunders ref The cell can also be destroyed by a process called antibody dependent cellular cytotoxicity , in which the pathogen does not need to be phagocytosed to be destroyed. During this process, the pathogen is opsonized and bound with the antibody IgG via its Fab domain. Then the antibody binds an immune effector cell via its Fc domain and this binding triggers a release of lysis products from the bound immune effector cell monocytes, neutrophils, eosinophils and natural killer cells . This process can cause inflammation of surrounding tissues and damage to healthy cells.

Unreferenced date January 2009 An antibody titer is a measurement of how much antibody an organism has produced that recognizes a particular epitope , expressed as the greatest dilution that still gives a positive result. ELISA is a common means of determining antibody titers. For example, the Coombs test indirect Coombs test detects the presence of anti Rh antibodies in a pregnant woman s blood serum . A patient might be reported to have an indirect Coombs titer of 16. This means that the patient s serum gives a positive indirect Coombs test at any dilution down to 1 16 1 part serum to 15 parts diluent . At greater dilutions the indirect Coombs test is negative. If a few weeks later the same patient had an indirect Coombs titer of 32 1 32 dilution which is 1 part serum to 31 parts diluent , this would mean that she was making more anti Rh antibody, since it took a greater dilution to abolish the positive test. There are two main kinds of titer testing that one can do. First there is the physical titer this titer gives one the concentration of virus particles per unit of measurement. The second way to measure viral titers is to perform an infectious titer level. This test tells one the concentration of infectious particles that have the ability to cause infection. A physical titer is much easier and faster to perform but does not always tell one if that level is an infectious amount or not. Many traditional Serology serological tests such as hemagglutination or complement fixation employ this principle. Such tests can typically be read visually, which makes them fast and cost effective in a low tech environment. The interpretation of serological titers is guided by reference values that are specific for the antigen or antibody in question a titer of 1 32 may be below the cut off for one test but above for another. A titer when referring to a library titration is the number of plaque forming units per milliliter. The reason why the titer is important is because we need ... more details

Antibody mimetics are organic compounds that, like antibodies , can specifically bind antigens , but that are not structurally related to antibodies. They are usually artificial peptide s or protein s with a molar mass of about 3 to 20 kDa . Nucleic acid s and small molecule s are sometimes considered antibody mimetics as well, but not artificial antibodies, Fragment antigen binding antibody fragment s and fusion protein s composed from these. Some types have an antibody like beta sheet structure. Common advantages over antibodies are better solubility , tissue penetration, stability towards heat and enzymes, and comparatively low production costs. Antibody mimetics are being developed as therapeutic and Medical diagnosis diagnostic agents. ref cite journal author Gebauer M, Skerra A title Engineered protein scaffolds as next generation antibody therapeutics journal Curr Opin Chem Biol volume 13 issue 3 pages 245 255 year 2009 month June pmid 19501012 doi 10.1016 j.cbpa.2009.04.627 url http linkinghub.elsevier.com retrieve pii S1367 5931 09 00068 4 ref Examples class wikitable Antibody mimetic Scaffold Molar mass Example drug Affibody molecule s ref name pmid18435759 cite journal author Nygren PA title Alternative binding proteins affibody binding proteins developed from a small three helix bundle scaffold journal FEBS J. volume 275 issue 11 pages 2668 76 year 2008 month June pmid 18435759 doi 10.1111 j.1742 4658.2008.06438.x ref Z domain of Protein A align right 6 kDa ABY 025 rowspan 2 Affilin s ref cite journal author Ebersbach H, Fiedler E, Scheuermann T, et al. title Affilin novel binding molecules based on human gamma B crystallin, an all beta sheet protein journal J.

Monospecific antibodies are antibodies that all have affinity for the same antigen . Monoclonal antibodies are monospecific, but monospecific antibodies may also be produced by other means than producing them from a common germ cell. Production Hybridoma cell Main Monoclonal antibodies Production Monoclonal antibodies are typically made by fusing the spleen cells from a mouse that has been immunized with the desired antigen with myeloma cells. However, recent advances have allowed the use of rabbit B cells. PrEST Another way of producing monospecific antibodies are by PrESTs. A PrEST protein epitope signature tag is a type of recombinantly produced human protein fragment. They are inserted into an animal, e.g. rabbit, which produces antibodies against the fragment. These antibodies are monospecific against the human protein. ref cite journal author Larsson K, Wester K, Nilsson P, Uhl n M, Hober S, Wern rus H title Multiplexed PrEST immunization for high throughput affinity proteomics journal J. Immunol. Methods volume 315 issue 1 2 pages 110 20 year 2006 pmid 16949094 doi 10.1016 j.jim.2006.07.014 ref Cautions Recent research has led to the discovery that unstable hinged monospecific antibodies may engage in a process leading to a decrease in their apparent avidity affinity. This process, termed Fab arm exchange, has led to theories about the dissemination of viral infections in patients given monospecific IgG4 therapeutic antibodies. Evidence is suggestive that this process is linked to the dissemination of PML in patients given Tysabri for MS. Following dosing unpredictability still reigns and mutations in the hinge of the antibody which may prevent Fab arm exchange in vivo should be considered when designing therapeutic antibodies.

Orphan date February 2009 Panel Reactive Antibody PRA is a blood test that is routinely performed on patients waiting for kidney transplant kidney and heart transplant s and measures anti human antibodies in the blood. The PRA score is given as a percentage and can be from 0 to 99 . The PRA represents the percentage of the U.S. population that the anti human antibody in your blood reacts with. Patients develop anti HLA Human Leukocyte Antigen antibodies from exposure to HLA of other humans through previous transplants, blood transfusions and or pregnancy. Patients showing high Panel Reactive Antibodies are often referred to as sensitized. Patients with high PRA usually 50 are less likely to receive transplants as the risk for immediate antibody mediated rejection of the transplanted organ is significantly increased. Treatments to reduce PRA in sensitized transplant candidates exist including treatment with Rituximab a B cell specific antibody , IVIg , protein A immunoabsorption, plasmapheresis etc. Reference Jordan and Pescovitz, Clin J Am Soc Nephrol 1 421 432, 2006 http cjasn.asnjournals.org cgi content full 1 3 421 .
