  • Publication number: 20230330234
    Abstract: It is provided a composition comprising a hyperbranched polyester polyol derivative and a small molecule comprising at least one cyclic amine. The hyperbranched polyester polyol derivative is obtainable by a method comprising the following steps: a) reacting only glycidol and ?-caprolactone at a temperature lying in a range of between 40° C. and 140° C. to obtain a hyperbranched polyester polyol derivative in which caprolactone residues and glycerol residues are randomly arranged; b) reacting the hyperbranched polyester polyol derivative of step a) with a sulfation reagent to obtain a sulfated hyperbranched polyester polyol as hyperbranched polyester polyol derivative.

  • Publication number: 20050037402
    Abstract: This invention relates to a device and a process for direct quantitative in vitro determination of a substance that is contained in a sample. The device according to the invention comprises agents, immobilized on a surface, for detecting substances, a free substance-emitter conjugate, and agents, immobilized on a surface, for detecting the emitter. The emitter of the device that is used comprises a portion that reacts with a change in the emission properties in an interaction with the agent for detecting the emitter. By means of the device according to the invention, substances that are selected from antigens, such as proteins, peptides, nucleic acids, oligonucleotides, blood components, serum components, lipids, pharmaceutical agents and compounds of low molecular weight or, in another design, substance-detecting agents, such as, for example, antibodies or fragments thereof, can be determined directly quantitatively, in, e.g., whole-blood samples.
