摘要:
The present application relates to a method of characterizing an agent's ability to increase insulin secretion in a subject. The method comprises determining whether the agent is able to modulate MAG level at the inner surface of the cytoplasmic membrane of a cell and/or ABHD6 activity. The agent is characterized as having the ability to increase insulin secretion in the subject when it is capable of upregulating MAG level at the inner surface of the cytoplasmic membrane and/or downregulating ABHD6 activity.

The present invention provides: a method of pretreating a serum or plasma sample for detection of a protein or a plurality of proteins of interest in a serum or plasma sample via mass spectrometry and a method of detecting such a protein or proteins, wherein proteins such as albumin present in abundance in a sample are removed in a convenient manner, thereby making it possible to collect digested peptides from the protein of interest. Specifically, the present invention provides a method of pretreating a sample for detecting proteins in a serum or plasma sample via mass spectrometry, comprising a step of adding a protease to the sample under non-denaturing conditions to digest proteins and a step of separating the obtained peptides from undigested proteins, and a method of detecting proteins, comprising subjecting the obtained peptides to mass spectrometry.

The present invention discloses a probe useful for the selective detection of metallo-beta-lactamases, in particular carbapenemases, thereby distinguishing those species of bacteria that are carbapenem-resistant from bacterial strains that are sensitive. Cephalospori based probes that have the 6,7 R,R configuration are susceptible to cleavage by beta-lactamases but cannot distinguish between cleavage by metallo-beta-lactamases and other beta-lactamases. By modifying a side group of the cephalosporin, selectivity can be introduced allowing the probes to distinguish between various types of metallo-beta-lactamases,
摘要:
The present invention relates to a method for detecting bacteriolytic conditions in a test sample comprising the step of contacting the test sample with a bacterial strain and a substrate which undergoes a detectable change when cleaved by a specific enzyme of said bacterial strain, wherein the bacterial strain is unable of: (a) uptaking the substrate from the medium and (b) secreting the enzyme specific for the substrate outside of the cell and wherein detecting a change in the test sample due to the cleavage of the substrate by its specific bacterial enzyme indicates that bacteriolytic conditions exist in the test sample. The invention further provides a kit for performing the method of the invention.
