摘要:
The invention relates to a component comprising a carrier composed of a structurable material with at least one through-opening which is closed off by a porous membrane, characterized in that the porous membrane projects from the surface of the component surrounding the through-opening. In many embodiments, the component also comprises a carrier substrate, wherein one side of the carrier substrate which points towards the component and the opposite side of the component preferably form a fluid duct, wherein in the preferred case the at least one through-opening of the carrier communicates on its non-closed side with the fluid duct. The component according to the invention is suitable for installation and for electrochemical measurement of trans-membrane proteins, preferably in double-lipid layers. The invention also proposes various methods for manufacturing the component.

摘要:
The invention relates to an improved cell-free protein synthesis method using a eukaryotic cell lysate in the presence of a caspase inhibitor, to a device for carrying out said method, and to the use of a caspase inhibitor for increasing the protein yield or for increasing the stability of the synthesized proteins in such a cell-free protein synthesis method using a eukaryotic cell lysate. In a preferred embodiment of the invention, the cell-free protein synthesis method is carried out as a continuous method in a device which comprises at least two compartments separated by a dialysis membrane. The translation reaction takes place in at least one first compartment, the reaction compartment, and during the translation reaction i) reactants are diffused from at least one other compartment, the supply and discharge compartment, into the reaction compartment, and ii) reaction byproducts are diffused from the reaction compartment into the supply and discharge compartment by means of the dialysis membrane. According to the invention, the caspase inhibitor is provided at least in the reaction compartment but can also be preferably provided in the supply and discharge compartment in order to supply unused inhibitors to the reaction compartment.
