Abstract: A microprocess part having at least one microfluid process element (4) and having microfluid channel connections (9) has a thermally insulating housing (1) surrounding the microfluid element (4), where the microfluid channel connections (9) are passed through the housing (1), and connecting elements for connecting individual housings (1) are arranged on the housing (1) in such a way that the microfluid channel connections (9) associated with each can be tightly connected to one another. The microfluid element (4) is arranged between a connection block (3) and a heat transfer block (2), where the temperature of the heat transfer block (2) and of the connection block (3) and thus also of the microfluid element (4) can be regulated. A connecting element for connecting individual housings (1) to one another has a conical screw (21) having a threaded section (22) and a conically tapering section (23).

Abstract: The present invention relates to a polymorphic CYP3A5 polynucleotide. Moreover, the invention relates to genes or vectors comprising the polynucleotides of the invention and to a host cell genetically engineered with the polynucleotide or gene of the invention. Further, the invention relates to methods for producing molecular variant polypeptides or fragments thereof, methods for producing cells capable of expressing a molecular variant polypeptide and to a polypeptide or fragment thereof encoded by the polynucleotide or the gene of the invention or which is obtainable by the method or from the cells produced by the method of the invention. Furthermore, the invention relates to an antibody which binds specifically the polypeptide of the invention. Moreover, the invention relates to a transgenic non-human animal. The invention also relates to a solid support comprising one or a plurality of the above mentioned polynucleotides, genes, vectors, polypeptides, antibodies or host cells.
