This invention relates to a rapid method for detection and characterization of stec bacteria based on the presence of nucleic acid sequences, in particular, to a pcr-based method for detection, and to oligonucleotide molecules and reagents and kits useful therefore. This method is preferably employed to detect stec bacteria in a food or water sample, such as a beef enrichment.

Chemical reagents for the activation of polysaccharides in the preparation of conjugate vaccines
This invention provides novel reagents for cyanating polysaccharides in aqueous or part aqueous solutions so that they may be covalently linked to proteins either directly or through a spacer. These reagents include 1-cyano-4-pyrrolidinopyridinium tetrafluoroborate (cppt), 1-cyano-imidazole (1-ci), 1-cyanobenzotriazole (1-cbt), or 2-cyanopyridazine-3(2h)one (2-cpo), or a functional derivative or modification thereof.

Alpha-1-antitrypsin compositions
A streamlined method for purifying alpha-1-antitrypsin (aat) from an aat-containing protein mixture, such as a cohn fraction iv precipitate, is provided. In the method of the invention, contaminating proteins are destabilized by cleavage of disulfide bonds with a reducing reagent, such as a dithiol, which does not affect aat.

Sensitive and rapid determination of antimicrobial susceptibility
The present invention relates to moving microorganisms to a surface, where they are grown in the presence and absence of antimicrobials, and by monitoring the growth of the microorganisms over time in the two conditions, their susceptibility to the antimicrobials can be determined. The microorganisms can be moved to the surface through electrophoresis, centrifugation or filtration.
