Abstract:
Methods and compositions are provided for specific binding assays in which specific binding reagents are immobilized on a solid phase. Immobilization is facilitated by covalently coupling specific binding assay reagents such as polypeptide receptors or analytes with water soluble polymers. Such water soluble polymers, for example star polymers such as dendrimers, provide production advantages of lot-to-lot uniformity and homogeneity, and can enhance sensitivity due to low non-specific binding to the solid phase.
Abstract:
Methods and compositions are provided for specific binding assays in which specific binding reagents are immobilized on a solid phase. Immobilization is facilitated by coupling bifunctional reagents to specific binding assay proteins thereby chemically cross-linking the specific binding assay reagents. Such cross-linked specific binding assay reagents provide the advantage of performing assays without the use of secondary reagents. This provides for enhanced sensitivity through minimizing nonspecific background interference with the solid phase or with the target samples.
Abstract:
A composition and method are disclosed to reduce the effects that endogenous alkaline phosphatase found in some human bodily fluid samples have on solid phase immunoassay systems. The composition comprises a detergent, inhibitors to alkaline phosphatase, and a buffer and may contain a substrate to alkaline phosphatase.
