Abstract
In today's security conscious environment rapid detection of explosives, such as pentaerythritol tetranitrate (PETN), the high energy material common in plastic explosives, is of critical importance. We evaluated two monoclonal antibodies and a rabbit polyclonal antibody, developed for the detection of PETN. Although these antibodies showed binding to bioconjugates of PETN as well as the hapten, PETN-succinate, we did not observe binding by free PETN. For demonstration of a competitive bead based fluid array immunoassay for PETN detection, we developed llama polyclonal antibody for the detection of free PETN. Our ultimate goal is developing anti-PETN single domain antibodies.
