20080199898 | COMPOSITIONS FOR THE DETECTION OF ENZYME ACTIVITY IN BIOLOGICAL SAMPLES AND METHODS OF USE THEREOF - The present invention provides for novel reagents whose fluorescence increases in the presence of particular proteases. The reagents comprise a characteristically folded peptide backbone conjugated to two fluorophores such that the fluorophores are located opposite sides of a cleavage site. When the folded peptide is cleaved, as by digestion with a protease, the fluorophores provide a high intensity fluorescent signal at a visible wavelength. Because of their high specificity and their high fluorescence signal in the visible wavelengths, these protease indicators are particularly well suited for detection of protease activity in biological samples, in particular in frozen tissue sections. Thus this invention also provides for methods of detecting protease activity in situ in frozen sections. | 08-21-2008 |

Devices for performing steps of the method are disclosed. | 05-12-2016 |
20160138073 | GLYCATED HEXAPEPTIDE OXIDASE AND USE THEREOF - The present invention provides a protein comprising an amino acid sequence in which arginine at position 61 of a protein comprising the amino acid sequence represented by SEQ ID NO: 1 is substituted to an amino acid selected from the group consisting of glycine, alanine, valine, leucine, serine, threonine, proline, cysteine, methionine, asparagine, glutamine, and aspartic acid; and a method for measuring a glycated hemoglobin in a sample, wherein the method comprises reacting a glycated hemoglobin in a sample with a protease to produce a glycated hexapeptide, then reacting the produced glycated hexapeptide with the aforementioned protein, and measuring a substance produced or consumed by the reaction. | 05-19-2016 |
20160159885 | INSECT METALLOPROTEINASE INHIBITORS - A polypeptide having at least 70% homology, in particular 80%, 90% or 95% homology to the polypeptide of SEQ ID NO:2 representing the wild-type of the protein insect metalloproteinase inhibitor IMPIα and having at least one mutation at position 35, 36 and/or 39 of the amino acid sequence of IMPIα and the polypeptide having an IC | 06-09-2016 |
