  • Quantitation of biomolecule in a complex mixture by serial combinatorial dilution
    Publication number: 20050136464
    Abstract: The invention provides a method for the quantification of a biomolecule in a complex mixture of biomolecules which comprises a fractionation of the mixture of biomolecules providing at least two fractions with at least one distinct component each. These fractions are then subjected to serial combinatorial dilution. Subsequently, the biomolecule is detected and identified in the fractions by a method providing a sensitivity threshold and identify information. The quantity of the biomolecule is determined by summarizing the number of identifications of the biomolecule in each fraction on each dilution level in consideration of the respective dilution factor. For purpose of normalization this sum may be divided by the total number of identifications of all biomolecules in all fractions on all dilution levels.

  • Nucleic acids encoding a protein conferring an inducible resistance to glycopeptide, particularly in gram-positive bacteria
    Patent number: 6569622
    Abstract: The invention relates to a protein VanB involved, in Gram-positive bacteria, in resistance to glycopeptides, particularly to vancomycine, said resistance being of the type inducible by the vancomycine and non-inducible by teicoplanine. The invention also relates to the utilisation of fragments of nucleotides of the gene van B for the detection of resistances to glycopeptides.

  • Laundry, dishwashing or cleaning product detergent portions with controlled release of active substance
    Publication number: 20010031714
    Abstract: The invention relates to a laundry, dishwashing or cleaning product detergent portion having two or more detersive components of which at least two are to be released into the liquor at different points in time in a laundering, dishwashing or cleaning process, said portion comprising at least one release controlling (physico)chemical switch which is not subject or not exclusively subject to temperature control, and also one or more substances for increasing the extent of the shift in pH.

  • Polynucleotides and their use for detecting enterococci and streptococci bacterial strains
    Patent number: 6054269
    Abstract: Polynucleotides and oligonucleotides for identification of species of the Streptococcus genus and the Enterococcus genus are provided. The polynucleotides and oligonucleotides are useful as probes and primers. Polypeptides expressed by the polynucleotides and oligonucleotides are useful for the preparation of monoclonal and polyclonal antibodies that recognize the polypeptides.
