  • immunological
  • The six main antigens used in immunological laboratories for detection are Ro, La, Sm, RNP, Scl-70 and Jo1, which are screened for by Ouchterlony double immuno diffusion techniques and confirmed by immunoblotting. (wikipedia.org)
  • Vaccines
  • Vaccines are examples of antigens in an immunogenic form, which are intentionally administered to a recipient to induce the memory function of adaptive immune system toward the antigens of the pathogen invading that recipient. (wikipedia.org)
  • HLAs
  • Defects in the structure of the HLAs is the cause of some diseases where the body's immune system perceives a host antigen as foreign and begins to attack the body's own tissue. (encyclopedia.com)
  • transplantation
  • Compatibility of ABH antigens has important impacts on the prognoses of transplants of kidneys, livers and hearts, but less so on marrow, bone or cornea transplantation prognoses. (wikipedia.org)
  • antibody
  • An illustration that shows how antigens induce the immune system response by interacting with an antibody that matches the antigen's molecular structure . (wikipedia.org)
  • The term antigen originally described a structural molecule that binds specifically to an antibody. (wikipedia.org)
  • What is the relationship between antigen and antibody and how does that relationship influence hemolysis? (enotes.com)
  • It can happen as a response to several different bacteria and parasites, as well as to the antigen/antibody reaction. (enotes.com)
  • This can be due to the natural life-span of a red blood cell, or it may be as a result of an antigen-antibody interaction. (enotes.com)
  • On anti-nuclear antibody tests, these antigens have a speckled pattern. (wikipedia.org)
  • Blood group Antigen Antibody Mohr, J. (1951). (wikipedia.org)
  • serological
  • Other heterophile antigen are responsible for some diagnostic serological test such as Weil felix reaction for typhus fever Paul bunnell test for infectious mononucleosis Cold aglutinin test in Primary atypical pneumonia Composition: chemically these are lipoprotein-polysaccharide complexes, possibly there are identical chemical groupings in the structure of mucopolysaccharids and lipids. (wikipedia.org)
  • phenotype
  • ABH antigens secretion, i.e. presence (phenotype: secretor - Se) or absence (nonsecretor: se) of ABO blood group system antigens in saliva, milk, sweat, amniotic fluid, urine, feces and other body fluids is one of the most famous polymorphism in the field of blood antigens in body excretions. (wikipedia.org)
  • receptors
  • Also, an antigen is a molecule that binds to Ag-specific receptors, but cannot necessarily induce an immune response in the body by itself. (wikipedia.org)
  • It was expanded to refer to any molecule or a linear molecular fragment that can be recognized by highly variable antigen receptors ( B-cell receptor or T-cell receptor ) of the adaptive immune system. (wikipedia.org)
  • Whether one T-cell receptor jointly recognizes a virus product in association with a class I antigen or whether separate T-cell receptors independently recognize the virus product and the class I antigen, respectively, is not yet resolved (for a recent review see ref. 2). (springer.com)
  • pathway
  • There are three compartements involved in this antigen presentation pathway: early endosomes, late endosomes or endolysosomes and lysosomes, where antigens are hydrolized by lysosome-associated enzymes (acid-dependent hydrolases, glycosidases, proteases, lipases). (wikipedia.org)
  • amino
  • The complete amino acid sequence of an HLA-DR antigen-like ß chain as predicted from the nucleotide sequence: Similarities with immunoglobulins and HLA-A, B, C antigens. (springer.com)
  • tissue
  • Because the HLA is a chemical tag that distinguishes "self" from "nonself," the antigen is important in the rejection of transplanted tissue and in the development of certain diseases (e.g., insulin-dependent diabetes). (encyclopedia.com)
  • Autoantibodies to these antigens are associated with particular connective tissue disorders. (wikipedia.org)
  • Methods
  • The antigen is a suspension of de-fatted leprosy bacilli which has been extracted with chloroform-ether and killed, either by heat, or by other effective methods. (wikipedia.org)
  • The two primary methods of antigen retrieval are heat-mediated epitope retrieval (HIER) and proteolytic induced epitope retrieval (PIER). (wikipedia.org)
  • bind
  • At the molecular level, an antigen can be characterized by its ability to bind to an antibody's variable Fab region . (wikipedia.org)
  • Both MHC class I and II are required to bind antigen before they are stably expressed on a cell surface. (wikipedia.org)
