  • Patent number: 6197594
    Abstract: The present invention concerns a method for the detection of an analyte in a sample liquid by luminescence measurement according to the principle of a ligand-receptor assay, e.g. an immunoassay or a hybridization assay or a combination thereof, wherein a sample liquid is incubated with at least one receptor which carries a luminescent label and the presence or/and the amount of the analyte to be detected is determined in the sample liquid by measuring the luminescence in a measuring medium containing dispersed components.

  • Patent number: 6190906
    Abstract: The invention provides an expression vector useful in expressing foreign genes in procaryotes. The vector consists of the promotor/operator region and initiation point of translation of the mg1 operon. This combination is referred to as a regulation sequence. In order to prepare this, desired portions of the mg1 operon are cut from the genome of a cell which can utilize galactose via appropriate restriction endonucleases. This is then inserted into a DNA vector.
