    • 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.
    • 本发明涉及用于直接定量体外测定样品中所含物质的装置和方法。 根据本发明的装置包括固定在表面上用于检测物质的游离物质 - 发射体结合物和固定在表面上的用于检测发射体的试剂。 使用的装置的发射器包括与用于检测发射器的试剂的相互作用中与发射性质的变化反应的部分。 通过根据本发明的装置,选自抗原的物质,例如蛋白质,肽,核酸,寡核苷酸,血液成分,血清成分,脂质,药物和低分子量的化合物,或者在另一种设计中, 物质检测剂,例如抗体或其片段,可直接在例如全血样品中定量测定。
