Development and evaluation of an enzyme-linked immunosorbent assay for dengue capsid.

ABSTRACT: The astonishing speed with which Dengue has spread across the world and the severity of its infection make Dengue a prime threat to human life worldwide. Unfortunately, to date there are no effective vaccines or treatments against Dengue. Since only a few assays permit rapid and sensitive detection of Dengue, we developed a specific antigen capture enzyme-linked immunosorbent assay (ELISA) for the abundant structural Dengue-2 capsid protein. We showed that the ELISA allows rapid and sensitive detection of Dengue-2 replication in various cell lines including human and mosquito cells. Using anti-capsid antibodies, we demonstrated that the capsid ELISA is as accurate as other well-characterized Dengue assays such as intracellular FACS staining (IFSA) and fluorescent focus (FFA) assays.
