Development of Enzyme-Linked Immunosorbent Assay for the Detection of Bt Protein in Transgenic Cotton

Enzyme-linked immunosorbent assays (ELISA) are being used extensively for the identification of Bt-protein in Bt transgenic crops. A sandwich ELISA test is the most preferable immunoassay for the quantification of Bt-protein in transgenic cotton plants. Here, we describe development of sandwich ELISA, employing polyclonal rabbit antibody as a capture antibody and HRP-labeled mouse anti-Bt protein-antibody as a detector antibody.
