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.
IgG is the most abundant of the five classes of immunoglobulins, representing about 80% of serum immunoglobulin protein. It is the major antibody in the secondary humoral response of immunity, serves to activate the complement system, and is frequently involved in opsonization.gG is the only immunoglobulin that crosses the placenta and is the major component of passive maternal antibody transfer via colostrum and yolk. IgM is the first antibody produced in the primary immune response.
