Human IgG for Interference Testing Catalog # B2013169 Lot # Batch Dependent Expiration Batch Dependent Amount 5 mg Concentration Not applicable Supplied as Powder Applications Biochemical interference testing and assay validation Storage –20°C Keywords Human IgG, Immunoglobulin G (IgG) Grade Biotechnology grade; ultrapure water, 0.22 µm filtered This high-purity Human IgG reagent is supplied as a lyophilized powder and optimized for interference testing in immunoassays, biochemical workflows, and analytical platforms. Immunoglobulin G (IgG) is the most abundant antibody isotype in human serum and plays a central role in immune response and assay interference. Its presence can affect signal detection, binding specificity, and assay reproducibility, making it a critical control material for validation studies. Packaged in 5 mg aliquots and stored at –20°C, this biotechnology-grade reagent is suitable for reconstitution in Type I ultrapure water (resistivity >18 MΩ·cm). It is ideal for developers evaluating IgG cross-reactivity, Fc receptor binding, and subclass-specific interference. The material is filtered through 0.22 µm membranes and processed under stringent quality controls to ensure consistency across batches. Compatible with ELISA, CLIA, lateral flow, and multiplex platforms. Key benefits: Human IgG powder for interference testing and assay validation Supports Fc receptor binding studies and subclass-specific analysis Filtered and aliquoted for reproducibility and long-term storage Compatible with immunoassay and biochemical platforms Biotechnology grade; reconstitutable in ultrapure water Indication for Use:This product is for Research Use Only (RUO). This product is not for administration to humans or animals. This product is not for human or veterinary diagnostic or therapeutic use. References:1: Bruhns P.
