An antibody is a Y shaped proteins that are cruical to the specific immune response and are released by lymphocytes. The top "arms" of the Y have sites that recognise and bind specfic counterparts, other proteins called antigens, on cells that are not SELF (cells that are part of the organism producing the antibodies). Each of the arms on one antibody recognises the same antigen as it partner arm and so each antibody binds two atingens. This mean that potentially two cells can be bound together and this is the primary function of antibodies, to bind masses of cells together making them inefctive at damaging SELF cells and as a mass they are phagocytosed by macrophages. Antibodies are also present on T-lymphocytes which use them to recognise non-self cell and directly destroy them.
What else can I help you with?
What is antibody and what you is the function?
Antibody is a type of protein produced by the immune system, its function is to fight antigens (bacteri, virus)
An antibody oponizes invading organisms is in order to enhance the function of?
To enhance the function of phagocytosis. The antibody binds to the antigen (on the organism). The antibody also binds to the phagocyte thus facilitating the coming together of the antibody and phagocyte and phagocytosis can then proceed.
What is the function of treponemal antibody tests?
Treponemal antibody tests are used to rule out false-positive results on reagin tests.
Which antibody function binds antibodies to soluble antigen molecules?
precipitation
What is the function of globulin's?
globulins are the proteins that acts as a antibody against pathogens..
What is the function of the globulins?
globulins are the proteins that acts as a antibody against pathogens..
What function of this protein is to bind to a specific antigen preventing it from attacking host cells?
Antibody.
Antibody molecules and receptor molecules are similar in that they both?
have a specific shape related to their specific function.
What is the function of an antigen in an antigen-antibody response?
To help immune cells identify and destroy a pathogen
What is an IgE antibody?
IgE is the antibody that causes acute allergic reactions; it is measured to detect allergic conditions. IgD, which constitutes the smallest portion of the immunoglobulins, is rarely evaluated or detected, and its function is not well understood.
What is the function of IgG?
IgG functions as an antibody that helps in phagocytosis of microbes and activates NK cells to kill the pathogen.
What is the function of the secondary antibody in an ELISA?
In an ELISA (enzyme-linked immunosorbent assay), the secondary antibody serves to bind specifically to the primary antibody that is attached to the target antigen. This secondary antibody is typically conjugated to an enzyme or a detectable label, allowing for the amplification of the signal. When a substrate is added, the enzyme reacts to produce a measurable signal, such as color change, which indicates the presence and quantity of the target antigen. Ultimately, the secondary antibody enhances the sensitivity and specificity of the assay.
