  • Patent number: 7348135
    Abstract: An assay for assessing the permeability of mitochondrial membranes is provided. The assay is based on enzymatic reactions that produce a detectable signal in the presence of intra-mitochondrial compounds. In some embodiments, the intra-mitochondrial compounds may be reduced and/or oxidized nicotinamide adenine dinucleotides (i.e., NADH and NAD+, respectively). The assay may optionally be provided in the form of a kit, and may further be useful in the discovery and interrogation of compounds that may serve to inhibit pathologic increase in mitochondrial membrane permeability, which is associated with numerous and varied mammalian disease.

  • Patent number: 7335286
    Abstract: The invention relates to measuring the concentration of analytes with the aid of an oxidase in an immersion sensor situated in a fluid or in a matrix containing fluid. Oxygen diffuses into the enzyme layer from within, from a gas-filled space connected to the atmosphere and/or to an oxygen reservoir. This enables oxygen saturation of the oxidase in a low-oxygen or oxygen-free medium and/or at high analyte concentrations. The analyte diffuses into the enzyme layer in a channel or a number of channels which contain(s) water and limit(s) diffusion, wherein the channel/channels on the surface of the sensor is/are filled with a protein-impermeable, hydrophilic matrix. By increasing the channel cross-section on the surface of the sensor and/or by connecting the channel/channels to a protein-impermeable, porous, hydrophilic layer on the surface of the sensor, the effect of outer deposits on the diffusion resistance of the analyte is reduced.

  • Patent number: 7291698
    Abstract: Novel synthetic enzyme substrates, enhanced to have improved enzymatic specificity, are disclosed. These synthetic enzyme substrates consist of a substrate peptide that has had its specificity further improved by additional synthetic moieties, selected by combinatorial chemistry techniques, that act to sterically block non-target enzymes. These “steric restrictor” moieties may be labeled to produce a detectable signal upon enzymatic reaction. These novel substrates are particularly useful for improved enzyme substrate microarrays. Specific applications for improved protease substrate microarrays are discussed.

  • Patent number: 7282482
    Abstract: This invention pertains to the discovery that nerve growth factor (NGF) is capable of preventing further demyelination of nervous tissue in pathologies characterized by the demyelination of nervous tissue (e.g. multiple sclerosis). In one embodiment, this invention provides a method for inhibiting demyelination in a subject having an inflammatory disease of a nervous tissue. The method involves administering an effective amount of NGF, an NGF analogue, or an active fragment of NGF where the effective amount is sufficient to downregulate the production of interferon ? by T cells infiltrating the central nervous system and/or to upregulate IL-10 production by glial cells.
