Patent ID: 7459306

Claim:
A process unit for providing a gap-shaped hybridization space to hybridize nucleic acid samples, proteins or tissue sections on a slide, comprising: a) at least one slide; b) at least one device closing the hybridization space and being able to move in relation to the at least one slide; c) an annular sealing surface to seal the hybridization space by application to a surface of the at least one slide; d) lines to introduce media to and remove them from the hybridization space; and e) a specimen supply line, wherein the device and each one of the slides limit a hybridization space that has relief structures in the form of depressions to block air bubbles, wherein the relief structures are located on a surface of at least one of the device and the slide, and wherein the depressions form line-less bubble traps, arranged entirely within the hybridization space.
