Use of polyvinyl derivatives for increasing signal intensity, useful particularly in immunoassays, reduces non-specific binding and improves both signal-to-noise ratio and dynamic range

摘要

Use of polyvinyl derivatives (A) for increasing the signal intensity with simultaneous reduction in non-specific binding. Independent claims are included for the following: (1) method for increasing signal intensity with simultaneous reduction in non-specific binding in which determination of bound analyte, on beads or planar arrays, is done in presence of (A); and (2) kit for performing an immunoassay that includes at least one buffer having (A) as a component.
