摘要:
The present invention relates to compounds that are substrates for an enzyme, and upon reaction with the enzyme provide a detectable response, such as an optically detectable response. In particular, the compounds have utility in detecting the presence of a β-lactamase in a sample. In addition to the compounds, methods are disclosed for analyzing a sample for the presence of a β-lactmase, for example, as an indicator of expression of a nucleic acid sequence including a sequence coding for a β-lactmase. Kits are disclosed that include the disclosed compounds and additional components, for example, cells, antibodies, a β-lactmase or instructions for using the components in an assay.

The present invention relates to polynucleotide and polypeptide molecules for stanniocalcin-2, a novel member of the stanniocalcin family. The polypeptides, and polynucleotides encoding them, modulate electrolyte homeostasis. The present invention also includes antibodies to the stanniocalcin-2 polypeptides.

A manually manipulated implement and method of use thereof for facilitating the drainage of conventional ostomy pouches are disclosed. The implement includes a two-piece handle portion with an elongated engagement member extending from each, with hinge means connecting the handle pieces and engagement members of movement toward and away from one another between spaced and essentially contacting positions. When the pouch drain opening is positioned over a suitable receptacle, the pouch walls are placed between the elongated engagement members, which are then moved from the spaced position to engage the pouch walls firmly therebetween. The implement is then moved manually toward the drain opening, forcing the contents out of the pouch, into the receptacle. In the preferred embodiment the implement is of one-piece molded plastic construction and includes means for stabilizing the relative lateral position of the engagement members as the implement is moved along the pouch.
摘要:
A recovery system recycles the washwater used to clean excess binder and debris from the production components, including a forming hoodwall constructed of non-corrosive materials, for manufacturing fiberglass insulation. A separate closed-loop recovery system is provided for the forming hoodwall in which the binder-containing washwater is screened and then recycled back to the forming hoodwall without further chemical treatment to change the pH level. A binder reclamation system is coupled to the hoodwall washwater recovery system to divert the low pH washwater when the supply of binder needs replenished at the forming hoodwall. The binder reclamation system introduces an acid solution to the cleaned washwater to lower the pH from about 2.5 to about 3.5. The other production components share a bulk washwater recovery system in which a base solution is introduced to raise the pH to approximately 8 or above to reduce corrosion in the other production components.
摘要:
A binder composition, obtained by polymerizing acrylic acid monomer in water in the presence of a cure accelerator comprising an alkali metal salt of a phosphorous-containing inorganic acid to form a low molecular weight polyacrylic acid and subsequently reacting said low molecular weight polyacrylic acid with a polyhydroxy crosslinking agent in a crosslinking step to make a composition suitable for use as a component in a binder for fiberglass. A significant improvement involves conducting the crosslinking step in the absence of added catalyst. Moreover, satisfactory results are obtained in the absence of conventional undesirable sulfur odors.
