Summary of the Inventive Concept

This inventive concept leverages the core technology of Shiga toxin A subunit effector polypeptides to develop novel applications in targeted agricultural pest control, environmental remediation, biomedical imaging, and veterinary diagnostics.

Background and Problem Solved

The original patent focused on cell-targeting molecules for site-specific conjugation, primarily for therapeutic applications. However, the limitations of this technology lie in its narrow scope, neglecting the potential of Shiga toxin A subunit effector polypeptides in other industries. This inventive concept addresses the need for targeted solutions in agriculture, environmental remediation, biomedical imaging, and veterinary diagnostics, offering a more comprehensive approach to utilizing this technology.

Detailed Description of the Inventive Concept

The new claims extend the original patent's technology to various industries, enabling the development of novel systems, methods, compositions, devices, and kits. For instance, the cell-targeting molecule can be designed to specifically bind to pest-specific biomolecules, facilitating targeted agricultural pest control. Similarly, the Shiga toxin effector polypeptide can be modified to target specific pollutant biomolecules, enabling environmental remediation. In biomedical imaging, the polypeptide can be engineered to emit a detectable signal upon binding to disease biomarkers. In veterinary diagnostics, the cell-targeting molecule can facilitate detection of disease-specific biomolecules.

Novelty and Inventive Step

The new claims introduce novel applications and use cases for Shiga toxin A subunit effector polypeptides, which were not originally considered in the original patent. The inventive step lies in the recognition of the potential of this technology in diverse industries and the development of innovative solutions to address specific problems in these fields.

Alternative Embodiments and Variations

Alternative embodiments may include varying the binding region to target different biomolecules, modifying the linker peptide to optimize conjugation, or using different Shiga toxin effector polypeptide modifications to achieve specific functions. Variations could also involve combining the cell-targeting molecule with other technologies, such as gene editing or nanotechnology, to enhance its capabilities.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in various industries, including agriculture, environmental remediation, biomedical imaging, and veterinary diagnostics. The market for targeted agricultural pest control alone is projected to reach $10 billion by 2025. The potential for environmental remediation, biomedical imaging, and veterinary diagnostics applications is substantial, with growing demand for innovative solutions in these fields.
