2. MONOCLONAL ANTIBODIES: 2.1. What are Monoclonal Antibodies? 2.1.1. “Clones” A clone is a group (family) of cells which come from a single parent cell that divides various times and are identical in all ways. In their structure, metabolic characteristics, functions, etc. 2.1.2. “Antibodies” An antibody is a protein which is produced by the human body’s immune system when it detects a substance that may be harmful (antigens like: bacteria, viruses, chemicals, parasites, etc). Antibodies are sometimes produced when the immune system mistakenly considers a healthy tissue, as a dangerous one, and creates antibodies against it. This is called an “autoimmune disorder”. [8] 2.1.3. “Antigens” An antigen can be any foreign substance capable…

lymphokines, whereas, B cells mature in the bone marrow with cell surface molecules of antibodies and BCR. This is one way of distinguishing between the two types of cell (Eales, 1999). Even though they both specifically recognise foreign molecules such as microorganisms and destroy them, also known as a specific immune response,…

ELISA (Enzyme-Linked Immunosorbent Assay) ELISA is a technique to detect and quantify substances like proteins, antibodies, and hormones. The target antigen is immobilized to the bottom of the well and then an antigen-specific detection antibody is added. The detection antibody makes it possible to measure results. The three most common formats of ELISA would be direct assay, indirect assay, and sandwich assay. In direct assay, the antigen immobilizes to the bottom of the well where a labeled…

Direct Coombs test is also called Direct Antiglobulin Test or DAT. This test is used for the detection of IgG or C3 antibodies which are attached to the RBC’s surface. These antibodies are important to be detected because they might sometimes cause anemia due to destruction of RBCs. DAT is mainly done on blood samples of newborns, especially when a newborn is suffering from jaundice. • Procedure: 1. Place the sample of RBCs to be tested in a 5 % suspension of isotonic saline. 2. Using a…

The proteome of M. paratuberculosis strain JTC303 CF was different from that of the CE. Specifically, CF proteins generally had lower pIs (4.4 to 5.5) and smaller masses (most s immune system loses control of the pathogen, or the pathogen begins active replication, the organism disseminates, and the host response shifts to a Th2 type immune reaction. The hallmark of this infection stage is production of detectable serum antibodies. A positive relationship has been shown between the level of…

Immunocytochemistry (ICC), which this lab is based on, is commonly used as a laboratory technique to anatomically observe the location of a specific protein or antigen in cells by the use of a specific primary antibody that binds to it. A staining reagent or chromagen is used to help detect certain proteins used in this experiment, called 3,3'-Diaminobenzidine (DAB). 3,3'-Diaminobenzidine (DAB) DAB, a derivative of benzene, is an organic compound, which is both chemically and thermodynamically…

3. Why a malaria vaccine is required? When microorganism enter the body, the immune system fight these foreign antigens by production of T or B-lymphocytes that produces antibodies, which effectively neutralize foreign invaders. Human body take several days to produces antibodies, while microorganism attack and multiply in the body and produce serious illness before immune system can fit back, this is a reason behind the vaccine manufacturing and development (CDC, 20175; Sarkander et al., 2016;…

Introduction There are multiple Immunological techniques or tests used for starting and measuring an immune response (1). Antibodies and antigens found in our immune system is done by immunoassays (2). The majority of immunological tests are based on the adaptive immune system. Substances recognized by our immune system are antigens. Injections are done by a trained health care professional to test for an immune response. The antibodies work together to fight antigens. Immunologists can inject…

article antibodies from healthy immune groups will somehow bind to heme and acquire the ability to recognize multiple antigens. It was originally thought that all antibodies bonded to their individual antigens in a lock and key sort of function. However, several similar studies, such as the experiment performed by Bayry et al, have led to a much different consensus. It has now been determined that many antibody molecules are capable of changing its conformation to allow for its flexible…

precipitins (antibodies) that produce an immune reaction only against the antigen or antigens that the person 's own red cells do not carry” (Forensic Science,2006). In others words what he discovered was that in order to have a successful transfusions it was important to determine the blood type. Safe transfusion are those between two people with the same blood. In 1992 another important discovery was made it was identify the fourth type of blood type AB. This type of blood can receive…
