Assignee:

3M Innovative Properties Company - St. Paul MN

International Classification:

C12Q 1/04

US Classification:

435 34

Abstract:

Methods of determining the amount of microorganisms present in a test sample. The methods include a) incubating the test sample with a growth media to form an incubated sample, wherein the growth media includes an enzyme substrate and the enzyme substrate includes an enzymatically hydrolyzable group and a fluorescent group, wherein microorganisms present in the test sample include an enzyme that hydrolyzes the hydrolyzable group from the fluorescent group to form a fluorescently detectable product, wherein the fluorescently detectable product has both an acidic and basic species; b) exciting the fluorescently detectable product with light having a wavelength of Exλiso for a time sufficient for the fluorescently detectable product to emit light, wherein Exλiso is the absorbance isosbestic point of the fluorescently detectable product; c) detecting light emitted at a wavelength of Emλ1; and d) quantifying the light emitted at the wavelength of Emλ1, wherein the quantity of the light emitted at the wavelength Emλ1 is indicative of the amount of microorganisms present in the test sample.

Abstract:

The described invention provides a low fouling, high particle density polymerization process and an olefin polymerization cocatalyst activator composition comprising a cross-linked polymer bead having a surface area of from about 1 to 20 m/g to which are bound a plurality of non-coordinating anions, where the polymeric support comprises ligands covalently bound to the central metal or metalloid atoms of said anions, and an effective number of cationic species to achieve a balanced charge. The invention also provides an olefin polymerization catalyst compositions comprising the reaction product of a) the foregoing cocatalyst activator, and b) an organometallic transition metal compound having ancillary ligands, at least one labile ligand capable of abstraction by protonation and at least one labile ligand into which an olefinic monomer can insert for polymerization. In a preferred embodiment, the polymeric support has a surface area of 10 m/g and is particularly suitable for use with high activity organometallic, transition metal catalyst compounds.
