A protein produced by lymphocytes that consist of two heavy chains, two light chains, and an oligosaccharide moiety
{i} antibody, any of several blood proteins which identify and disable infectious foreign bodies; part of the blood serum that contains antibodies (Immunology)
A general term for the kind of globular blood proteins that constitute antibodies A tetrameric protein composed of two identical light chains and two identical heavy chains Specific proteins produced by derivatives of B lymphocytes that interact with and help protect an organism from specific antigens
An immunoglobulin is one of a class of structurally related proteins consisting of two pairs of polypeptide chains, one pair of light (L) low molecular weight chains and one pair of heavy (H) chains, all four linked together by disulfide bonds On the basis of the structural and antigenic properties of the H chains, Ig's are classified (in order of relative amounts present in normal human serum) as IgG, IgA, IgM, IgD and IgE Antibodies are Ig's, and all Ig's probably function as antibodies
(abbreviation Ig) - another name for antibody; there are five major classes: IgA, IgD, IgG, IgM, and IgE
a general term for antibodies, which bind to invading organisms, leading to their destruction There are five classes of immunoglobulins: IgA, IgG, IgM, IgD and IgE (See also antibody )
A structural protein consisting of two pairs of polypeptide chains Variations of these chains allow different types of antibodies to be formed by the body
n (ih-MYOO-no-GLOB-yoo-len) Glycoprotein that acts as an antibody and is produced by white blood cells during an immune response Immunoglobulins are found in blood serum, the respiratory and digestive tracts, and body secretions They are grouped into five classes on the basis of their structure and physiological activity: IgG, IgM, IgA, IgD and IgE IgG takes part in various immune responses of the body to bacteria or foreign substances such as allergens, tumor or transplanted tissue
The different classes of proteins comprising antibodies, e g IgA, IgG, IgM, & IgE Each type has a different structure and function For example, IgA antibodies are found in saliva, tears, respiratory and alimentary tract secretions and protect against viruses and bacteria IgE is involved in allergic reactions like hayfever
One of a family of closely related though not identical proteins capable of acting as antibodies, abbreviation Ig (CMD 1997)
Immune globulin; an antibody or, more generally, antibodies which provide protection against infectious agents Immunoglobulins are produced by lymphocytes of the B cell type in response to the stimulation of infectious agents or the contents of vaccines Immunoglobulins are soluble proteins present in blood serum and other body fluids Temporary protection via immunoglobulins can be transferred to another person through injection of a purified portion of a donor's serum
also known as antibodies, they are proteins (gamma-globulins) produced by B lymphocytes differentiated in plasma cells They consist of heavy chains (a, d, e, g, m) and light chains (k, l) and are divided into IgA, IgD, IgE, IgG, IgM according to which heavy chains contain them They have different functions according to the class to which they belong The molecule they bind with is called an antigen
The class of antibodies produced predominantly against ingested antigens, found in body secretions such as saliva, sweat, or tears, and functioning to prevent attachment of viruses and bacteria to epithelial surfaces
The class of antibodies found only on the surface of B cells and possibly functioning as antigen receptors to initiate differentiation of B cells into plasma cells
The most abundant class of antibodies found in blood serum and lymph and active against bacteria, fungi, viruses, and foreign particles. Immunoglobulin G antibodies trigger action of the complement system
one of the most common of the five major classes of immunoglobulins; the chief antibody in the membranes of the gastrointestinal and respiratory tracts
antibodies or proteins found in blood and tissue fluids produced by cells of the immune system to bind to substances in the body that are recognized as foreign antigens Immunoglobulins sometimes bind to antigens that are not necessarily a threat to health and provoke an allergic reaction
One of a class of structurally related proteins Classified (in order of relative amounts present in normal human serum) as IgG (80%), IgA (10-15%), IgM (5-10%), IgD (less than 0 1%), and IgE (less than 0 01%)
A family of similar but distinctly different proteins which act as antibodies of five major types (IgA, IgD, IgE, IgG, and IgM) They are produced in lymphoid tissue by B lymphocytes and plasma cells, in response to the presence of antigenic substances
Proteins also known as antibodies, produced by certain cells of the immune system called B-lymphocytes Immunoglobulins bind to foreign antigens to help destroy them
Immunoglobulins, also known as antibodies, are proteins found in blood and in tissue fluids Immunoglobulins are produced by cells of the immune system called B-lymphocytes Their function is to bind to substances in the body that are recognized as foreign antigens (often proteins on the surface of bacteria and viruses) This binding is a crucial event in the destruction of the microorganisms that bear the antigens Immunoglobulins also play a central role in allergies when they bind to antigens that are not necessarily a threat to health and provoke an inflammatory reaction
Immunoglobulins are a class of proteins that function as antibodies, vital for protection against infection and disease They are divided into five classes: IgA, IgD, IgE, IgG, IgM on the basis of struicture and biological activity A variety of immunoglobulins can be found intact in Colostrum
sterile solution of globulins derived from the blood plasma of a person who has been immunized for tetanus; provides short-term immunization against tetanus in cases of possible exposure to the tetanus bacillis
