IgG4 Latex kit

For the reliable measurement of subclass concentrations Binding Site assays utilize highly specific, affinity purified, polyclonal antisera raised in sheep using patented technology.

Binding Site IgG Subclass assays are optimized for use in the investigation of antibody deficiencies. Latex-enhanced reagents are provided for the measurement of IgG3 and IgG4 enabling accurate quantitation of deficient subclass levels as well as levels at the lower end of pediatric normal ranges.

Calibration of an assay against an internationally recognized reference preparation will ensure that sample results remain accurate and consistent. In 2009 Williams et al. assigned IgG subclass values to the international serum protein reference material DA470K which is the most commonly used reference material for commercial IgG assays. All Binding Site IgG subclass assays were subsequently calibrated against DA470K.
