Uses
Anti-Human Polyvalent Immunoglobulins (whole molecule)-FITC antibody may be used for immunofluorescence of human peripheral blood lymphocytes at a working antibody dilution of 1:128. For anti-nuclear antibody assay of acetone-fixed rat liver cells, a minimum dilution of 1:128 is recommended. For direct labeling of human tonsil sections, a dilution of 1:80 may be used. This antibody was used to stain C2C12 cell line derived from mouse myoblasts at a dilution of 1:100
General Description
IgG antibody subtype is the most abundant serum immunoglobulins of the immune system. It is secreted by B cells and is found in blood and extracellular fluids and provides protection from infections caused by bacteria, fungi and viruses. Maternal IgG is transferred to fetus through the placenta that is vital for immune defence of the neonate against infections. IgA antibody is secretory antibody and is present abundantly in mucous linings of gastrointestinal, respiratory and genitourinary tracts, tears and saliva. IgM antibodies are present as pentamers in the serum and are produced in response to antigens
Purified human IgA, IgG and IgM are used to develop anti-sera in rabbits. The IgG fraction of each anti-sera is purified and conjugated to Fluorescein Isothiocyanate (FITC), in an alkaline reaction. Anti-Human Polyvalent Immunoglobulins (whole molecule)-FITC antibody specifically recognizes human IgA, IgG and IgM.
Biochem/physiol Actions
IgG (immunoglobulin G) antibody provides protection from infections caused by bacteria, fungi and viruses. Maternal IgG is transferred to fetus through the placenta that is vital for immune defense of the neonate against infections. IgG antibody participates in complement fixation and opsonization.
