How are monoclonal antibodies made in the process of creating targeted therapies for various diseases?
Monoclonal antibodies are made by isolating a specific antibody-producing cell and fusing it with a cancer cell to create a hybrid cell called a hybridoma. This hybridoma can produce large quantities of identical antibodies that target specific proteins on diseased cells, making them a key component in targeted therapies for various diseases.

What are the key differences between human and humanized monoclonal antibodies in terms of their effectiveness and safety profiles in treating diseases?
Human monoclonal antibodies are derived from human cells and are less likely to cause immune reactions in patients. Humanized monoclonal antibodies are partially derived from non-human sources and may have a higher risk of immune reactions. In terms of effectiveness, both types of antibodies can be effective in treating diseases, but human monoclonal antibodies may have a slight advantage due to their fully human origin.
How can one create monoclonal antibodies?
Monoclonal antibodies are created by fusing a specific type of immune cell, called a B cell, with a cancer cell to form a hybrid cell called a hybridoma. This hybridoma cell can then produce large quantities of identical antibodies that target a specific antigen. These monoclonal antibodies can be used for various medical purposes, such as diagnosing and treating diseases.
What is the Contribution of biotechnology in the field of medicine?
Biotechnology has massively contributed to medicine by enabling the development of advanced therapies like genetically modified organisms for insulin production, personalized medicine through genetic testing, and biopharmaceuticals like monoclonal antibodies for treating diseases such as cancer. It has revolutionized drug discovery, diagnostics, and treatment methods, leading to better healthcare outcomes and improved patient care.
How does the body's immune system work in creating antibodies to fight off infections and diseases?
The body's immune system creates antibodies to fight off infections and diseases by recognizing harmful substances, called antigens, and producing specific proteins called antibodies to target and neutralize them. This process helps the body to defend against pathogens and prevent illness.
Why did Cesar Milstein win The Nobel Prize in Physiology or Medicine in 1984?
The Nobel Prize in Physiology or Medicine 1984 was awarded jointly to Niels K. Jerne, Georges J.F. Kohler and Cesar Milstein for theories concerning the specificity in development and control of the immune system and the discovery of the principle for production of monoclonal antibodies.
What diseases are being treated with monoclonal antibodies?
Monoclonal antibodies are commonly used to fight a large number of diseases including cancer. The monoclonal antibodies fight the disease by targeting a certain antigen and recruiting the body's natural immune system to destroy the antigen-infected cells.
What are the key differences between human and humanized monoclonal antibodies in terms of their effectiveness and safety profiles in treating diseases?

Which two ways that biotechnology can be used to treat diseases?
Biotechnology can be used to treat diseases through the development of targeted therapies, such as monoclonal antibodies, which specifically attack cancer cells while sparing healthy tissue. Additionally, gene therapy allows for the correction of genetic disorders by introducing, removing, or altering genetic material within a patient's cells to address the underlying causes of diseases.
What is the value of monoclonal antibody technology?
Monoclonal antibodies can be used to protect against disease, help diagnose a wide variety of illnesses and detect the presence of drugs or viral and bacterial products. It is these specific traits that make it so valuable.
Are monoclonal antibodies use in immunotherapy?
Yes, Herceptin is a drug used in certain form of breast cancer which overexpresses the HER-2 protein, enabling angiogenesis and rapid tumour growth. Herceptin is the trade name for monoclonal antibodies against the HER-2 receptor which block these, limiting their function and improving patient prognosis. There are other examples to, monoclonal antibodies against IgE antibody to prevent type 1 hypersentivity e.g. peanut allergy.
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.
How might monoclonal antibodies be useful in criminology wildlife management or archaeology?
In criminology, monoclonal antibiodies are useful in distinguishing adult serum stains from those of a fetus's or newborn's serum in cases of illegal abortion or infanticide. (A new method uses sensitive detection of α-fetoprotein AFP in the stains.) In wildlife magaement it can be used to determine and map animals with diseases. An example is rabies. Monoclonal antibiodies can be used in archeology to identify archeological disoveries.

What are the principles of monoclonal antibody?
monoclonal antibodies lies on the principal of producing antibodies and monocloaal means the specificity and avidity for antigen i.i they recognize a single epitope. firstly the mouse is innoculated with appropriate antigen and spleen cells are isolated from it. then the myeloma cells grown in vitro and spleen cells which are isolated are fused in the polyethyleneglycol (PEG) and cultured in HAT medium. the following result comes; 1. spleen cells die in vitro 2. spleen-myeloma hybrid cells survive 3. unfused myeloma cells die in HAT medium surviving hybrid cells are clonned and used further.
