Abstract: The present invention relates to a contact lens for diagnosis and treatment of dry eye syndrome. The contact lens, according to the present invention, may diagnose dry eye syndrome by means of a change in an electric current occurring as a result of a field effect when a dry eye syndrome biomarker binds to a probe, and when dry eye syndrome is diagnosed, generates an electric current so that a gold film blocking a drug reservoir melts by the electric current, thereby enabling the release of a drug to be controlled.

Abstract: The present invention relates to a method of purifying native ubiquitin without acid or heat treatment. The method presented here is designed to overcome limitations of acid or heat based ubiquitin purification in two different points of view. First, it decreases a chance of mixing other proteins resistant to acids or heat. Second, it includes no harsh condition, which might denature the ubiquitin. As a result, the purification of native ubiquitin becomes possible. The ubiquitin obtained herein is expected to be used for various purposes in technical fields.
