Patents by Inventor Emi Wada

Emi Wada has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Kit for determining the acetylation level of a peptide based on sensitivity of the peptide to peptidase
    Patent number: 7256013
    Abstract: The acetylation level of a peptide is determined utilizing the fact that the changes in the acetylation level are reflected in the sensitivity of the substrate peptide to a peptidase. This method can be used for measuring activities of deacetylase and acetylase, and also enables screening for substances that influence the activity of these enzymes. The deacetylase activity can be measured by a simple procedure according to the present invention.
    Type: Grant
