Solar panel refers to a panel designed to absorb the sun's rays as a source of energy for generating electricity or heating. A photovoltaic (in short PV) module is a packaged, connected assembly of typically 6Ã10 solar cells.
IgM vs IgG. An immunoglobulin or antibody refers to proteins that bind to antigens in specific cases. Both IgM and IgG refer to a class of immunoglobulin. Antibodies are produced by the immune system to fight antigens like bacteria and viruses. IgM refers to those antibodies that are produced immediately after an exposure to the disease, while IgG refers to a later response.
The binding of the Fc portion of IgG to the receptor present on a phagocyte is a critical step in the opsonizing property IgG provides to the immune response. Phagocytosis of particles coated with IgG antibodies is a vital mechanism to cope with microorganisms. IgG is produced in a delayed response to an infection and can be retained in the body for a long time. The longevity in serum makes IgG most useful for passive immunization by transfer of this antibody. Detection of IgG usually indicates a prior infection or vaccination.
