Measuring device for the quantitative photometric detection of biomolecules in the low density region (low - density - biochips)

摘要

Measuring apparatus for automated quantitative photometric detection of biomolecules in the low density region, comprisinga detection reaction, a guide unit (1) with one or more containers (2) for auxiliary solutions and a container (3) for receiving waste solutions as well as to - (4) and discharge lines (5) to the containers (2, 3),a measuring unit (6), with a means (7) for the photometric, pixel-oriented detecting a color reaction of at least one reaction solution with at least one biomolecule to be detected,a computer-based operating evaluation unit (13) for evaluating the measurement results,a measuring cassette (9) comprising a low density biochip (14) with a provided with functionalized reaction areas glass - or plastic support, wherein the measuring cassette (9) via at least one insertion opening (15) for the sample to be analysed (16) or samples has,the detection reaction, a guide unit (1) at least one receiving region (8) for the in-register receiving a measuring cassette and the latter via connections for the to - and outlet lines of the container (2, 3) for auxiliary solutions and waste solutions, wherein on the..
