Abstract

Compounds linked to a solid support through a divalent linker moiety are disclosed. In particular, compounds such as 1-hydroxybenzotriazole-6-carboxylic acid are directly linked to the support under mild conditions (i.e., in aqueous or organic solvents at neutral pH and at room temperature). The polymer bound 1-hydroxybenzotriazole-6-carboxylic acid can be used for the derivatization of amines as well as for single step amino group modification of proteins, peptides, and amines via acylation or sulfonylation reactions. A flow through device and method for the single step amino group modifications of proteins, peptides, and amines is disclosed. Also disclosed is a flow through device for the detection of amines in a sample. Additionally, a device and method for the detection of amines in a sample using 1-hydroxybenzotriazole-6-carboxylic acid are disclosed. In a preferred embodiment, the device is used to detect the presence of amines in a spoiled meat product. Diagnostic kits for detecting the presence of amines are also disclosed.
