Abstract: A cell culture substrate for cultivating adherent cells, including: a substrate (S), a polymer (P) comprising amino groups, which is bonded to the substrate, and a saccharide (Z) having at least two monosaccharide units for attaching the adherent cells, wherein the saccharide (Z) is covalently bonded to the polymer (P) via the amino groups. Such a cell culture substrate is suitable for cultivating adherent cells and allows the cells to be detached from the cell culture substrate in a gentle manner by adding a saccharide.

Abstract: The invention relates to a method for producing polyclonal antibodies against an antigenic target protein which comprises inducing an immune response in a host by applying an immunogenic composition comprising membrane vesicles incorporating said antigenic target protein to said host and obtaining antibodies against said target protein from the host's serum.

Abstract: 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.

Abstract: The invention relates to a component, comprising a carrier made of a structurable material with at least one continues opening which is closed by a porous membrane, characterized in that the porous membrane protrudes from the surface of the component surrounding the continuous opening. In some embodiments, the component further comprises a carrier substrate, wherein a side of the carrier substrate which faces the component and the opposite side of the component preferably form a fluid channel, wherein the at least one continuous opening of the carrier preferably communicates on its open side with the fluid channel. The component according to the invention is suitable for the installation and electrochemical measuring of transmembrane proteins, preferably in lipid bilayers. The invention also proposes different methods for producing the component.
