Abstract
A specific binding composition comprises a specific binding species and one or more water-soluble proteins or carbohydrates, substantially none of which has a pI greater than about 5. This composition provides improved sensitivity with lower background in diagnostic tests. Preferably, the species is labeled for detection, for example, with an exzyme. The composition can be included with a dye-providing composition in a diagnostic test kit for use in diagnostic methods.
