is a sterile preparation of concentrated antibodies (immune globulins) recovered from pooled human plasma processed by cold ethanol fractionation. 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 immune globulins are broadly classified into five types on the basis of physical, antigenic and functional variations, labeled respectively IgM, IgG, IgA, IgE and IgD.

a class of proteins produced in lymph tissue in vertebrates and that function as antibodies in the immune response

A crude preparation of antibody molecules collected from pooled multiple blood donations, used as a means for passively transferring antimicrobial resistance to susceptible individuals.

A protein found in the blood that fights infection. Also known as gamma globulin.

A biological preparation that consists of proteins from human blood plasma. These proteins react with foreign proteins to form antibodies that aid in the boy's defense against infections.

a sterile protein solution made from human plasma containing the gamma globulin protein fraction. This product is used to enhance the body's immune response when it is exposed with a disease causing antigen.

Gamma globulin part of plasma.
