Alkaline phosphatase is coupled to immunoglobin G antibody in a one-step procedure using the homobifunctional reagent glutaral-dehyde, which reacts with amino groups in the two proteins. The procedure is simple to perform and requires minimal equipment. 

The most common method of labeling immunoglobin G (IgG) antibody with this enzyme uses the homobifunctional reagent glu-... 

The isothiocyanate derivatives of fluorescein and rhodamine are widely used to label antibodies. They react with the amino groups of the immunoglobin G (IgG) molecule under alkaline conditions and a molar excess of about 20 is usually optimal. More recently, N-...

Polystyrene beads are known for their capacity to bind immunoglobin G globulins nonspecifically, by hydrophobic interaction, so that the immu-nospecificity of the Fab region is preserved. Because of the dipolar nature of the phenyl ring, polystyrene probably represents a surface capable of extraordinary interaction with hydrophobic regions of proteins.

Antibodies are produced by mammals as part of an immune response of the host to foreign intruders such as microorganisms, viruses, bacteria, and parasites. Antibodies are otherwise called immunoglobins and are heavy globular plasma proteins (150 kDa). Antibodies can be classified in to five classes IgG, IgM, IgA, IgE, and IgD. Immunoglobin G (IgG) is the most abundant immunoglobin species in serum and also the most commonly used...
