The heart of every PV system is the array of photovoltaic modules. Today, the overwhelming majority of PV modules (more than 95%) are crystalline silicon, made from the second most abundant element on earth.
A. IgG and IgM are short for immunoglobulin G and immunoglobulin M. Immunoglobulins are also known as antibodies and are substances produced by the body's immune system in response to foreign substances such as bacteria, viruses, fungi or other substances like animal dander or cancer cells.gG antibodies are important for fighting bacterial and viral infections. IgG antibodies are the only type of antibody that can cross the placenta, therefore the IgG antibodies of a pregnant woman can also help protect her baby in its initial weeks of life before its own immune system has developed.
Selective IgA Deficiency is defined as a primary immunodeficiency characterized by an undetectable level of immunoglobulin A (IgA) in the blood and secretions but no other immunoglobulin deficiencies. There are five types (classes) of immunoglobulins or antibodies in the blood: IgG, IgA, IgM, IgD and IgE.IgG is present in the largest amount, followed by IgM and IgA. IgD is much lower, and IgE is present in only minute amounts. IgM and IgG mainly protect us from infections inside our body tissues, organs and blood.here are five types (classes) of immunoglobulins or antibodies in the blood: IgG, IgA, IgM, IgD and IgE.
