First Claim
Patent Images
1. A glucose biosensor for in vivo or in vitro use comprising:
- a) at least one mutated binding protein and at least one reporter group attached thereto such that said reporter group provides a detectable and reversible signal change when said mutated binding protein is exposed to varying glucose concentrations;
wherein said detectable and reversible signal change is related to said varying concentrations.
