The present invention relates to a simple, sensitive colorimetric capture ELISA for BoNTs with detection limits at or below 1 mouse unit. The assay is reproducible and accurate with negligible cross-reactivity between serotypes. The strength of the assay relies on its novel format and the unique preparation of the antibodies used in the assay. The antibodies are affinity-purified to the heavy chain C-fragment of the toxin. Others have used antibodies, which are not affinity purified or which are purified to the whole toxin molecule. We reasoned that since the C-terminal region of the heavy chain is where the binding domain is located, this portion of the molecule should not be covered by associated proteins, if the binding domain is located, this portion of the molecule should not be covered by associated proteins; if the binding domain was blocked, then the molecule would be precluded from binding to the cell surface and would not be toxic. Thus, the binding region “looks” the same in both the purified and complex forms. Antibodies to this region should recognize preparation of the antibodies is that they do not cross-react between serotypes, they recognize neutralizing epitopes, and they recognize purified and complex toxins equally.Start Signature
