Abstract:
1. An assembly comprising a multiple immunoassay apparatus and a sample, wherein the multiple immunoassay apparatus comprises: (a) at least two antibody-introducing units, wherein each antibody-introducing unit introduces a respective antibody into the apparatus; (b) at least two microchannels, through each of which a fluid containing said respective antibody flows, wherein each microchannel is connected to each antibody-introducing unit; (c) at least two reaction units in which the antibody reacts with the sample in an immunohistochemical pattern wherein each reaction unit is formed from a portion of the respective microchannel, each reaction unit contacts the sample, and each reaction unit comprises an open part toward the sample such that when the fluid containing a respective antibody flows through the microchannel between the reaction unit and the sample, the fluid contacts a portion of the sample via the open part and an immune reaction take place in each reaction unit; (d) at least one fluid outlet through which the fluid containing the respective antibody is discharged outside the apparatus from the reaction units; and (e) a pressurizing unit that compresses the reaction unit toward the sample; wherein the sample is one piece of tissue.
