Abstract
A .beta.-galactosyl-umbelliferone-labeled conjugate of the formula: ##STR1## wherein --NH)L is a protein or polypeptide, such as an immunoglobulin, bound through an amino group thereof, n is an integer from 2 through 10, m is an integer from 1 through 10, and p is on the average from 1 to the number of available amino groups in L. An intermediate in the synthesis of such labeled conjugate is also provided. The labeled conjugates are useful as reagents in specific binding assays (e.g., immunoassays) for determining the conjugated protein or polypeptide, or a specific binding analog or partner thereof, in liquid media.
