Abstract
The present invention relates to a DNA aptamer binding specifically to tuberculosis specific antigen 7.7 kDa (TB7.7), a biosensor for diagnosis of tuberculosis, comprising the same, and a method for providing information for diagnosis of tuberculosis. The present inventors found that not only does a DNA aptamer according to the present invention have specific binding potential to TB7.7 protein, but also the binding affinity is excellent. When used, the DNA aptamer of the present invention can be thus expected to exhibit greater stability than a conventional ELISA method using an antibody. Hence, the aptamer is expected to find useful applications in the development of compositions for tuberculosis diagnosis, biosensors for tuberculosis diagnosis, and information providing methods for tuberculosis diagnosis.
