Expedeon Signs Supply Deal for Colloidal Gold With Reszon Diagnostics

NEW YORK (360Dx) — Expedeon said today that it has signed a three-year supply agreement for its colloidal gold with Malaysia-based Reszon Diagnostics International.

According to Heidelberg, Germany-based Expedeon, its colloidal gold is an aqueous suspension of uniform, spherical metallic nanoparticles that can conjugate to antibodies and antigens. Under the terms of the deal, Expedeon will supply the colloidal gold to Reszon for use in its diagnostic lateral flow assays, which include tests for lymphatic filariasis, typhoid fever, and malaria.

Reszon will also evaluate Expedeon's InnovaCoat gold nanoparticles — which feature a proprietary surface coating that covalently binds antibodies or proteins to form stable conjugates — for increasing the sensitivity of its currently marketed lateral flow assays.

Additional terms were not disclosed.

"This agreement is the second just this month for our colloidal gold in Asia, further validating Expedeon as a global supplier for the diagnostics industry," Expedeon CEO and CSO Heikki Lanckriet said in a statement.

Earlier this month, Expedeon inked a supply deal for its colloidal gold with South Korean diagnostics firm PaxGenBio.
