Cry2A LFS kit for Corn/Cotton

Cry2A lateral flow strips (LFS) test kit is intended to be used for the qualitative detection of Cry2A protein in individual cotton/corn leaf or seed samples. The total incubation time of the assay is 5 minutes.


An antibody specific to the Cry2A protein molecule is immobilized on the test line area of nitrocellulose membrane. Second antibody specific for Cry2A molecule is conjugated with colloidal gold and incorporated in the sample area of lateral flow strip. Anti mouse IgG is immobilized on the control line area of the LFS. When the LFS is placed in the sample extract, the Cry2A protein present in the sample extracts binds to the antibody labelled with gold nano particles and the complex moves upward by capillary action. The complex then binds to the antibody coated on the test line resulting in pink/purple color test line. As the complex moves further up, it binds to the control line resulting in pink/purple color control line. In absence of Cry2A, the test line does not appear as no complex binds to the test line while control line turns pink/purple color indicating validity of the test protocol.

Cross-reactivity: The Cry2A LFS kit does not cross react with CP4EPSPS (RoundUp Ready**), Cry1F, Cry1Ac, eCry3.1Ab
(AgriSure Duracade), Cry3Bb, Cry1Ab, Vip3A, Cry34Ab1, Cry35Ab1 or PAT (LibertyLink***).
