Processing and Microfiltration of Mosquitoes for Malaria Antigen Detection in a Rapid Dot Immunobinding Assay

Abstract

Data on a technique for the detection of antigen from arthropod vectors in a dot immunobinding assay are presented. In this system, antigen present in the vector was first solubilized in sodium dodecyl sulfate. The homogenate from this process was microfiltered through a two-membrane sandwich; target antigen molecules passed through the first membrane and were immobilized on the second one. The first membrane was nonbinding and served to impinge debris. The second membrane was a high-protein-binding-capacity hydrophobic polyvinylidene difluoride membrane. High signal-to-noise ratios were produced by this method, which is readily adaptable for field use. This assay was used for malaria sporozoites, but it can serve as a general technique that is applicable to other arthropod vectors and etiologic agents. Reprints.
