Igg1
Igg1
Igg1 (pronounced as "eye-gee-gee-one") is a subclass of the Immunoglobulin G (IgG) antibody. It is one of the four subclasses of IgG, which are IgG1, Igg2, Igg3, and Igg4.
Etymology
The term "Igg1" is derived from the term "Immunoglobulin G subclass 1". The prefix "Immunoglobulin" is derived from the Latin words "immunis" meaning exempt and "globus" meaning sphere, referring to the protein's role in the immune system. The "G" stands for "gamma", which is the type of heavy chain found in many subclasses of antibodies. The "1" denotes the subclass.
Function
Igg1 is the most abundant IgG subclass found in the blood and extracellular fluid, allowing it to control infection of body tissues. By binding many kinds of pathogens such as viruses, bacteria, and fungi, Igg1 ensures they are unable to multiply and cause disease. It is also involved in the activation of complement and ADCC.
