General description

Diethylenetriamine-pentaacetic acid pentasodium salt is an organic chelating agent.

Application

Diethylenetriamine-pentaacetic acid pentasodium salt solution may be used in a competitive indirect enzyme-linked immunoassay for the quantitative measurement of lead ions. It may be used in one-step immunochromatographic assay (ICA) for the fast detection of lead ions in water samples.

Immunoassays for quantitative measurement of environmental heavy metals offer several advantages over other traditional methods. To develop an immunoassay for lead, Balb/c mice were immunized with a lead-chelate-protein conjugate to allow maximum exposure of the metal to the immune system.

One-step immunochromatographic assay (ICA) has been developed using colloidal gold-labeled monoclonal antibody probe for the rapid detection of lead ions in water samples. The ICA was based on the theory of competitive reactivity, and the results can be easily judged
