Monoclonal antibodies are highly specific, targeting a single antigen, while polyclonal antibodies can target multiple antigens. Monoclonal antibodies are produced from a single clone of cells, resulting in uniformity, while polyclonal antibodies are produced from multiple clones of cells, leading to variability.

What are the key differences between polyclonal antibodies and monoclonal antibodies in terms of their specificity and production methods?

Polyclonal antibodies are produced by multiple B cells and are a mix of antibodies that target different epitopes on an antigen, resulting in broader specificity. Monoclonal antibodies are produced by a single B cell clone and target a single epitope on an antigen, leading to higher specificity. Polyclonal antibodies are typically produced by immunizing animals, while monoclonal antibodies are generated through hybridoma technology or recombinant DNA technology.


What is a sentence that has polyclonal in it?

Polyclonal antibodies showed up in the blood test.Rabbits are the most common animal for polyclonal antibody production.Chickens are sometimes used for polyclonal antibody production.


What is the difference between rhogam and immunoglobulin?

Immunoglobulin is a general term referring to a sort of protein in the immune system which is generally synonymous with the term Antibody. Rhogam is a treatment administered to pregnant women which are bloodtype Rh- but carrying bloodtype Rh+ fetuses. This prevents hemolytic disease of the newborn in which mom's immune system recognizes the baby as foreign and begins attacking the baby's cells. Rhogam is a type of polyclonal antibody (pooled from the serum of many different women) treatment (aka an immunoglobulin) which essentially "tricks" mom's immune system into thinking she already has immunity to the baby's cells that are being recognized as "foreign". Therefore, mom's immune cells are tricked into ignoring the baby's cells and thus not attacking them. This is a very basic and crude definition, I suggest a textbook for more detailed explanation.

What are monospecific Polyclonal Antibodies?

Monospecific Polyclonal antibodies are produced by not just a common germ cell like monoclonal antibodies, but from other products. Monospecific antibodies have affinity for the same antigen.


What is the advantage of using monoclonal antibodies?

A single clone, ie a bunch of identical antibodies. As opposed to polyclonal antibodies, which are different clones even though they bind the same antigen.


Why polyclonal antibody tend to have cross-reaction compare to monoclonal antibody?

Polyclonal antibody recognizes several epitopes on the target protein while monoclonal antibody recognizes only single epitope, hence monoclonal antibodies are more specific than polyclonal antibodies. However, sometimes MAbs are not able to precipitate the antigen because the epitope might need to be exposed on the surface of the antigen to be recognized by the antibody. Since some of the epitope might be hidden and it's a single epitope that is recognized by the monoclonal antibody, the propability of the antibody to reconize the epitope is lower compared with the polyclonal antibody that recognizes several epitopes on the target protein this is the reason for the tendency of polyclonal antibodies to have cross-reaction as compared to MAbs. by Victor S Gruezo Jr

Construction and fermentation of Antibody drug?

Monoclonal antibodies (mAb or moAb) are monospecific antibodies that are made by identical immune cells that are all clones of a unique parent cell, in contrast to polyclonal antibodies which are made from several different immune cells. Monoclonal antibodies have monovalent affinity, in that they bind to the same epitope. Given almost any substance, it is possible to produce monoclonal antibodies that specifically bind to that substance; they can then serve to detect or purify that substance. This has become an important tool in biochemistry, molecular biology and medicine. When used as medications, the non-proprietary drug name ends in -mab (see "Nomenclature of monoclonal antibodies"), and many immunotherapy specialists use the word mab anacronymically.

Why polyclonal antibody solution is able to precipitate its antigen protein whereas monlclonal antibody solution has hard time to do so?

Polyclonal antibody recognizes several epitopes on the target protein while monoclonal antibody recognizes only single epitope. Sometimes, monoclonal antibodies are not able to precipitate the antigen because the epitope might need to be exposed on the surface of the antigen to be recognized by the antibody. Since the epitope might be hidden and it's a single epitope that is recognized by the monoclonal antibody, the propability of the antibody to reconize the epitope is lower compared with the polyclonal antibody that recognizes several epitopes on the target protein.

Exciting New Treatments For Cancer And Autoimmune Diseases?

Antibodies are produced by the body's immune system when an infection occurs. Under normal circumstances, the antibodies that are produced recognize a broad range of targets, for example, different parts of a virus or bacteria. Each specific antibody is known as a clone, and the normal response to an infection is a polyclonal response, because many different specificities are represented.Polyclonal antibodies purified from animals are commonly used tool in biological research. However, the polyclonal nature of antibodies can be detrimental, as the exact specificity is unknown. In order to overcome these complications, scientists developed a method for generating monoclonal antibodies (mAbs), i.e., antibodies of a single specificity. Ultimately, the development of the technology for producing monoclonal antibodies resulting in the presentation of the 1984 Nobel Prize in Physiology or Medicine to Niels Jerne, Georges Kohler and Cesar Milstein.Immediately following the development of monoclonal antibodies, these reagents were primarily utilized as research tools. Subsequently, mAbs have been developed into important diagnostic tests including pregnancy tests, HIV screening tests, and cancer diagnostics.More recently, monoclonal antibodies have been developed for the treatment of a number of different diseases. Thus far, this type of biological therapy has been FDA-approved for the treatment of various cancers and autoimmune diseases as well as the prevention of rejection of transplanted organs.Monoclonal antibody treatment of cancer is effective because the antibody can be used to block pathways that drive the growth of the cancer cells or inhibit the ability of the tumor to drive the development of new blood vessels that are required to supply the growing tumor with nutrients. In the case of autoimmune disease, including multiple sclerosis, psoriasis, Crohn's disease and rheumatoid arthritis, monoclonal antibody therapies can block the cells that cause damage from entering the tissues they target or they can block the ability of the cells to function. Similarly, monoclonal antibodies can be used to prevent rejection of transplanted organs, a response that is driven by activation of the immune system.Monoclonal antibodies are an exciting new avenue of intervention for diseases that have traditionally been very difficult to treat. Research regarding this approach is ongoing, and new drugs are being approved frequently. For example, the FDA has approved two new monoclonal antibody drugs in the first quarter of 2011 alone, illustrating the rapid progress of this new tactic for treating chronic diseases.


What do you mean by Rheumatoid arthritis factor?

Rheumatoid factor (RF or RhF) is an antibody that attacs an organism's own tissue. omos often found in About 80% of people with rheumatoid arthritis have detectable rheumatoid factor. Those who do not are said to be "seronegative".Rheumatoid factor can also be a (antibody that precipitates on cooling of a blood sample); it can be either type 2 (monoclonal IgM to polyclonal IgG) or 3 (polyclonal IgM to polyclonal IgG)


What is disadvantges of fluorescence microscopy?

Florence microscopy has 3 main different way to make the cell fluorescence each with the disadvantages. Label protein outside the cell and microinject it - Takes a long time for little results You can use Immunofloresence which is faster by direct or indirect. Indirect you get better results through more floresence and takes less time because you can order the antibodies off the internet. You can use GFP gene and insert it into the cell. What you can do is have a plasmid transfect it then the protein will glow - This has a downside if the protein doesnt fold. If you are doing the immunofloresence you need to prepare the cell. You need to kill it to use the antibodies. You use formaldhyde or gluteraldehyde or methanol for this. This will but everything in place (cytoplasm wont move) then use a detergent to punch holes in the membrane. Then you use your anti-bodies to go into the cell and attach to your primary proteins. that you want to see. To make these antibodies you can proceed either by monoclonal or polyclonal. inject the rabit or w/e animal with an antigen. You will get antibodies forming with the epitop to that antigen that antigen should be the protein you want. Polyclonal have more then 1 epitope. and you need the rabit to do this.. if it dies bye bye antibodies disadvantage Monoclonal have Hybridomas which are immortal cell lines, they regognize only 1 epitope. Myeloma cell with a lymophocytes. To make sure you only have there hybridoma cell you can put them in HAT which will kill the myloma cells and you only get hybridomas.
