any of 5 classes (IgM, IgG, IgA, IgE, IgD) of antibody.
when administered, an antibody that confers short-term immunity; immune gamma globulin (IGG) provides passive protection against viral infections such as hepatitis A, measles, rubella, and varicella; immune globulin (human) (IGH) is used to prevent hepatitis B.
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.

Immunoglobulins are antibodies that fight disease by damaging foreign organisms that invade the body. Certain immunoglobulins such as IgG and IgM act as a primary defense against invading bacteria. Deficiency of these antibodies can result in recurrent infections, which can provoke recurrent asthmatic symptoms, ear infection, sinusitis, and pneumonia. Increased levels of IgE are usually associated with allergy symptoms.

The membrane-bound version of antibody that binds antigens and signals the B cell to secrete antibodies.
A protein produced by plasma cells and lymphocytes and characteristic of these types of cells. Immunoglobulins play an essential role in the body's immune system.

Types of antibodies that provide short-term immunity against disease.
A protein molecule capable of acting as an antibody.
A specific protein that is produced by specialized B-cells (plasma cells) against an antigen to aid in fighting infection. Some immunoglobulins (gamma globulins) take part in various immune responses of the body to bacteria or foreign substances (allergens, tumor or transplanted tissue). (Also called antibody.)Examples include IgG, IgM, IgA, IgD and IgE.

Only plasma that has tested negative for a) hepatitis B surface antigen (HBsAg), b) antibody to human immunodeficiency virus (HIV), and c) antibody to hepatitis C virus (HCV) is used to manufacture IG. IG is administered to protect against certain diseases through passive transfer of antibody. The IGs are broadly classified into five types on the basis of physical, antigenic and functional variations, and labelled respectively IgM, IgG, IgA, IgE and IgD.
A protein that acts as an antibody.
A protein molecule functioning as a specific antibody; it brings about the humoral phase of immunity.
A general term for all antibody molecules. Each Ig unit is made up of two heavy chains and two light chains and has two antigen- binding sites.
Also known as antibodies, these proteins are found in blood and in tissue fluids. Immunoglobulin 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. Immunoglobulin also plays a central role in allergies when they bind to antigens that are not necessarily a threat to health and provoke an inflammatory reaction.
An alternative name for antibody.

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.

Proteins with antibody activity that play an essential role in defending the organism against foreign proteins. Also known as antibodies and gamma globulins, they're induced by and released into the bloodstream in response to infections.

Immunoglobulins are the most important and most prevalent immune factors in bovine colostrum.
