Antibodies are involved in the immune response. They're made up of two light polypeptide chains and two heavy polypeptide chains bonded together. Antibodies have a variable region which acts in a similar way to the active site of an enzyme. Each antibody has a variable region that is the complementary shape for a particular antigen and

The reason that I choose the medical field is because since I was a child, I've always helped my mom who suffered from MS. Her condition made her suffer from not being able to a lot of things on her own such as, cooking cleaning and bathing herself. My mom had multiple strokes in her lifetime that would cause her not being able to take care of herself. I would definitely say that you will have to be a strong person to help take care of those in need. It has prepared me for all the ups and downs which An RN will have to endure in their career such as learning how to handle people who cannot care for their self's. it made it easier for me to choose what I wanted to do in life. Especially preparing for her death. On January 16, 2016 my mom's fight with MS finally ended. I watched her lay there which one of the hardest

a. This function is mediated by T cells and B cells (memory cells) in our body via adaptive immunity. The adaptive immune system evolved in early vertebrates and allows for a stronger immune response as well as immunological memory, where each pathogen is “remembered” by a signature antigen. The adaptive immune response is antigen-specific and requires the recognition of specific “non-self” antigens during a process called antigen presentation. Antigen specificity allows for the generation of responses that are tailored to specific pathogens or pathogen-infected cells. The ability to mount these tailored responses is maintained in the body by memory cells. Should a pathogen infect the body more than once, these specific memory cells are used to quickly eliminate it. So basically killer T cells will identify antigens present on foreign cells. These antigens are not found in any of the cells inside our body. Therefore, T cells will identify them and kill them.

disease or ill health, by intercepting this pathogen the lymphoid localises it and isolates it from

Dr. Morris Greenberg was one of the two investigators and was the Health Department’s chief epidemiologist. He was not convinced that the men suffered from food poisoning, because the symptoms appeared too quickly. He postulated that the men had consumed some type of drug. To prove his claim, he wanted blood samples from the men and wanted the samples to be tested for methemoglobin, a compound formed

Have you ever thought of getting a job that pays you the most? Personal Financial Advisor and biomedical engineering are two different major fields that differ in many aspects, but pays very good. People usually tend to go for the field that they are mostly interested in ,and some people go for the one that pays better. Personal advisors requires more work to be done mentally than physically they “ provide advice on investments, insurance, mortgages, college savings, estate planning, taxes, and retirement to help individuals manage their finances”(Occupational Outlook Handbook). Unlike, biomedical engineering, it requires a lot of physical work to an addition of mental work and they “work in manufacturing, universities, hospitals, research

ELISA works on the principle of an antigen binding to specific antibody (lock and key), which can be used as a way to identify quantities of proteins in a small sample of fluid. The specific proteins used in an ELISA are estimated quantitatively. The ELISA test is carried out by incubating the serum that contains the antigen of interest with antibody’s within a well, in order for the antibody’s to bind with the specific antigens. The plate is then washed with a mild detergent in order to remove any proteins that have not been bound. The washing of the plates is carried out between every step in order

makes antibodies (also called immunoglobulins) that help attack and kill germs. Lymphocytes are in many areas of the body, such as lymph nodes, the bone marrow, the intestines, and the bloodstream.

A clarified and physiologic buffered (pH 7 to 8) is added to the antibodies and purified ZA2GP to form a mixture that is added to the immobilized ligand.

Question 1. I remember hearing in your video something about our body natural immunity and it eradicates the virus. The immune system includes physical barriers, such as the skin and mucous membranes that prevent pathogens from entering the body, and cellular responses, such as circulating macrophages that respond to foreign invaders. Our acquired immune system mounts a specific antibody response when the body is exposed to a foreign invader, and our immune cells attack the invader

When the body becomes infected with an illness, it relies on the immune system to fight the illness by allowing white blood cells to begin producing proteins, called antibodies. Antibodies then create a counter offense to decimate the infectious germ that has most likely already caused the body to have symptoms of the illness. The antibodies and immune system then work together to eliminate the virus and help heal the body. Consequently, these antibodies don’t leave the body, they lurk within the bloodstream on the look-out for other invaders, no matter the amount of time it takes for the body to become infected once again. Antibodies are specific to which the virus they are trying to eliminate. For example, an antibody that exterminates

Antigens are substances that provoke an immune response (they're the ultimate target for the immune system). Antibodies are simply proteins that are secreted as a result of the antigen provoked immune response. In short, antigens cause the disease and

When the pathogen replicates different components of immune system evolves to protect against various types of pathogens. However infection of an organism does not necessarily shows diseases, disease are only present when the bolus of infection, in terms of when immunity is comprised. All components of

Immunoglobulins are also known as antibodies and they are glycoproteins that are produced by plasma cells. These antibodies are the line of defence against foreign particles such as viruses and bacteria in our human bodies. This is why so much research has been conducted to gain more understanding and knowledge on this protein. The more we know the behavior, structure and function of this protein, the more doors will be open in the field of medicine in fighting off these foreign particles. The interesting aspect of immunoglobulins is that they specifically bind to specific antigens to fight them off such as a specific bacteria or virus, so the specificity of these proteins is very interesting and complex

For the immune system to able to keep us healthy it needs to be able to recognise what is a danger to our body and therefore needs to be removed, and what is safe. Proteins are used to do this. Pathogens have proteins on their surface called antigens, which activate the immune system. Our own cells also have surface proteins which the immune system recognises as part of the body and therefore doesn’t attack. (1)
