摘要:
Sterilization indicators that include a neutralizer, such indicators useful for testing the effectiveness of a sterilization procedure by measuring the activity of an active enzyme whose activity is correlated with the survival of microorganisms.
摘要:
Polymeric beads and methods of making the polymeric beads are described. The polymeric beads are crosslinked hydrogels or dried hydrogels. The polymeric beads are formed from droplets of a precursor composition that are exposed to radiation. The droplets are totally surrounded by a gas phase. The precursor composition contains a polar solvent and a polymerizable material miscible in the polar solvent. The polymerizable material has an average number of ethylenically unsaturated groups per monomer molecule equal to at least 1.2.
摘要:
Materials for use in miniaturized arrays, the arrays, and methods of manufacturing. Materials for making arrays described include a substrate with a silicon-containing layer, optionally with linking agents and reactants.
摘要:
Insoluble supports are prepared which possess high surface areas and efficiently dispersed isocyanate groups. These reactive supports are useful for covalently binding proteins which preferably are enzymes and provide catalysts for conducting organic reactions.
摘要:
Insolubilized enzyme particulates are located on the upstream surface of a filtration layer of a filtering element which can be used in a cartridge filter. Employed in a recycling flow reaction system at relatively high flux rates, the cartridges are useful for conducting catalyzed chemical reactions of dissolved solutes, for example, esterifications, isomerizations, oxidations, reductions, and cyclizations.
摘要:
A medium for electrophoresis comprises:(a) a polytetrafluoroethylene (PTFE) fibril matrix, and(b) particulate, electrically mobile ions, and sufficient liquid in the interstitial spaces of said matrix to allow for ion transport,the ratio of said particulate to PTFE being in the range of 99:1 to 4:1 by weight, and said ions being present in said liquid in an amount to provide a solution of concentration in the range of 1 to 1000 millimolar.Preferably the medium is self supporting.

摘要:
A method of separating a target biological species from a fluid is disclosed comprising contacting the fluid with a ligand-functionalized polymer comprising: a water soluble or water dispersible aminopolymer functionalized with guanidinyl groups; whereby a complex comprising the functionalized substrate and the target biological species is formed.
摘要:
The disclosure provides processes and systems for sterilizing an object using a sterilant gas. In some embodiments, the sterilant gas is produced by the thermal decomposition of a salt. Compositions to generate sterilant gasses are also disclosed.
摘要:
Surface coatings including azlactone-functional hydrogels and articles with the coatings disposed thereon are disclosed. Methods of making the coating and controlling the gellation time of the hydrogels are also disclosed.
