Sieved ultraspherical polynomials: In mathematics, the two families c(x;k) and B(x;k) of sieved ultraspherical polynomials, introduced by Waleed Al-Salam, W.R.CD4 immunoadhesin: CD4 immunoadhesin is a recombinant fusion protein consisting of a combination of CD4 and the fragment crystallizable region.SeroconversionImmunoglobulin heavy chainLennox–Gastaut syndromeImmunoglobulin light chainFramework region: In molecular biology, a framework region is a region in the variable domain of a protein which belongs to the immunoglobulin superfamily, and which is less "variable" than the CDR.Immunoglobulin class switching: Immunoglobulin class switching, also known as isotype switching, isotypic commutation or class-switch recombination (CSR), is a biological mechanism that changes a B cell's production of immunoglobulin (antibodies) from one type to another, such as from the isotype IgM to the isotype IgG. During this process, the constant-region portion of the antibody heavy chain is changed, but the variable region of the heavy chain stays the same (the terms "variable" and "constant" refer to changes or lack thereof between antibodies that target different epitopes).Polyclonal B cell response: Polyclonal B cell response is a natural mode of immune response exhibited by the adaptive immune system of mammals. It ensures that a single antigen is recognized and attacked through its overlapping parts, called epitopes, by multiple clones of B cell.Fragment antigen-binding: The fragment antigen-binding (Fab fragment) is a region on an antibody that binds to antigens. It is composed of one constant and one variable domain of each of the heavy and the light chain.ATC code J06: ==J06A Immune sera==Diary TourEva Engvall: Eva Engvall, born 1940, is one of the scientists who invented ELISA in 1971.Eva Engvall, The Scientist 1995, 9(18):8Somatic hypermutation: Somatic hypermutation (or SHM) is a cellular mechanism by which the immune system adapts to the new foreign elements that confront it (e.g.PlasmacytomaAnti-idiotypic vaccine: Anti-idiotypic vaccines comprise antibodies that have three-dimensional immunogenic regions, designated idiotopes, that consist of protein sequences that bind to cell receptors. Idiotopes are aggregated into idiotypes specific of their target antigen.Coles PhillipsSecretory componentMonoclonal antibody therapyHypogammaglobulinemiaSymmetry element: A symmetry element is a point of reference about which symmetry operations can take place. In particular, symmetry elements can be centers of inversion, axes of rotation and mirror planes.Colostrum: Colostrum (also known colloquially as beestings,Gottstein, Michael. Colostrum is vital ingredient to keep newborn lambs alive.Hyperimmune globulin: Hyperimmune globulin is similar to intravenous immunoglobulin (IVIG) except that it is prepared from the plasma of donors with high titers of antibody against a specific organism or antigen. Some agents against which hyperimmune globulins are available include hepatitis B, rabies, tetanus toxin, varicella-zoster, etc.Raji cell: Raji cell line is the first continuous human cell line from hematopoietic origin. The cell lines produce an unusual strain of Epstein-Barr virus which will both transform cord blood lymphocytes and induce early antigens in Raji cells.Immunoelectrophoresis: Immunoelectrophoresis is a general name for a number of biochemical methods for separation and characterization of proteins based on electrophoresis and reaction with antibodies. All variants of immunoelectrophoresis require immunoglobulins, also known as antibodies, reacting with the proteins to be separated or characterized.Protein primary structure: The primary structure of a peptide or protein is the linear sequence of its amino acid structural units, and partly comprises its overall biomolecular structure. By convention, the primary structure of a protein is reported starting from the amino-terminal (N) end to the carboxyl-terminal (C) end.
