Question
Hybridomas are useful in biotechnology because They are cell lines that can in principle live forever They produce a monoclonal antibody They are made from B cells which can grow well outside the body All of the above are useful properties of hybridomas Some of the above are useful properties of hybridmos Herceptin is an antibody developed to treat breast cancer. It works as follows: Binds to the HER2 receptor when overexpressed in breast cancer cells. Prevents into and further cell division Binds to the Her3 receptor of breast cancer cells and promotes proliferation of Herceptin is found in the bloodstream to bind to breast cancer antigens and prevent cancer from spreading All of the above Some of the above. In addition to products such as Herceptin, commercially prepared antibodies can also these EXCEPT: As recombinant vaccines In fluorescence activated cell sorting For ELISA for diagnosis and testing. Visualization of molecules inside living cells All of the above are uses for commercially prepared antibodies. All of the following represent potential problems with attenuated vaccines EXCEPT A mutated virus might revert back. Immunocompromised patients might become ill with these vaccines. Much research is required to identify safe but effective changes in the All of these are potential problems. Which of the following procedures were used in developing a vaccine for vaccinology? A library of different proteins was expressed and purified in E. coli The proteins were screened for the presence on cell surfacesExplanation / Answer
1. Hybridomas are produced by injecting a specific antigen into a mouse, collecting an antibody-producing cell from the mouse's spleen, and fusing it with a tumor cell called a myeloma cell. The hybridoma cells multiply indefinitely in the laboratory and can be used to produce a specific antibody indefinitely. So, correct answer is option D.
2. Herceptin works by attaching itself to the HER2 receptors on the surface of breast cancer cells and blocking them from receiving growth signals. By blocking the signals, Herceptin can slow or stop the growth of the breast cancer. Herceptin is an example of an immune targeted therapy. Option A is correct.
3. Question number 3 is not fully visible. Some parts are cut.
4. Option D is correct. Attenuated vaccine is a vaccine created by reducing virulence of a pathogen, but still keeping it viable.
