Abstract
Methods for synthesizing an ALP conjugate are provided. The methods may include activating a carboxyl group of the ALP with a carbodiimide, to generate an active ester; and adding the substance to be conjugated such that a synthetic reaction occurs between the active ester and the substance to be conjugated, to generate an ALP conjugate.
Claims25
A method of synthesizing an alkaline phosphatase (“ALP”) conjugate, comprising:
- activating a carbonyl group of ALP with a carbodiimide to form an active ALP ester;
- and
- adding a substance to be conjugated;
- wherein the active ALP ester reacts with the substance to be conjugated to generate an ALP conjugate.

A kit for obtaining an enzyme conjugate, wherein the kit comprises a carbodiimide and ALP.
A method of synthesizing an enzyme conjugate, comprising:
- activating a carbonyl group of an enzyme with a carbodiimide, under acidic conditions between about pH 4.0 and about pH 5.0, to form an active ester;
- and
- adding a substance to be conjugated selected from at least one of the following:
- a peptide, a protein, an antigen, an antibody, and Staphylococcus protein A;
- wherein the active ester reacts with the substance to be conjugated to generate an enzyme conjugate.
