Description_x000D_ General description_x000D_ Monoclonal Anti-Goat IgG (mouse IgG1 isotype) is derived from the hybridoma produced by the fusion of mouse myeloma cells and splenocytes from an immunized mouse. IgG (immunoglobulin G) antibody subtype is a predominant serum immunoglobulins of the immune system. It is secreted by B cells and is found in blood and extracellular fluids. IgG is found in four subclasses IgG1, IgG2, IgG3 and IgG4. IgG has a monomeric structure._x000D_ The antibody reacts with an epitope located on the heavy chain of goat IgG1 and IgG2._x000D_ Physical form_x000D_ Solution in 0.01 M sodium phosphate buffer, pH 7.4, containing 1% inactivated bovine serum albumin and 15 mM sodium azide_x000D_ Disclaimer_x000D_ Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals._x000D_ Biochem/physiol Actions_x000D_ 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. Goat antibodies against many analytes are widely used in research as primary antibodies in various assay techniques. Second antibodies are that used to detect goat antibodies may lack specificity for goat immunoglobulins, and in many instances will also recognize other immunoglobulins that appear in the preparation being tested. This results in the need for extensive adsorption of the second antibody. Therefore, using a monoclonal antibody to goat IgG that is devoid of a binding capacity to other species can serve as a useful tool in many applications.
