Abstract
The present invention relates to a method and a device for determining a concentration of a biological active substance in a sample by the means of an enzyme-linked immunosorbent assay (ELISA). The device comprises a solid support within a tubing () for binding an immunosorbent and an inlet () for fluids, a detector () for detecting radiation due to an activity in said tubing (), wherein said tubing () is arranged inside a microchip () extending substantially in one plane, for conducting the fluids along the plane of the microchip (). Said tubing () forms a reaction cell having a large detection area (). The reaction cell of the microchip () is arranged perpendicular to the detector (). The method comprises the steps of introducing the fluids into the tubing (), conducting the fluids through the tubing () forming a reaction cell, in which reaction cell the radiation emitting activity takes place, and detecting the light emitted from the reaction cell substantially perpendicular to the plane.
