OBT1988G is a unique formulation specifically designed for use with anti-IgG-HRP conjugates. This diluent contains proprietary non-mammalian protein additives which will not interfere with anti-IgG-HRP conjugates used in antigen-down and sandwich ELISA formats (it does not contain BSA). These additives also provide additional structural stability to the IgG-HRP conjugate protein complex. OBT1988G will also inhibit conjugate binding to non-specific serum proteins bound to the plate, thus reducing conjugate bridging on the plate surface and lowering background noise.
