Detection of Transgenic Proteins by Immunoassays.

Rapid development and global cultivation of genetically modified (GM) crops necessitated the use of analytical tools that detect GM crops throughout the product life cycle. Antibody-based immunoassays such as enzyme-linked immunosorbent assays (ELISA) are instrumental in detecting protein expression in transgenic plants. These analytical tools are used throughout development, regulatory registration, commercialization, and stewardship of biotech products. Here we describe the Cry1F ELISA analytical method protocol, data generation and review, and troubleshooting of technical challenges.
