Abstract: The present invention refers to a method for the separation of host cell proteins (HCPs), antibody fragments and low molecular weight substances from solutions containing antibodies.

Abstract: The present invention relates to a method for an improved preparative separation of proteins, particularly monoclonal antibodies (mAB) from its associated charge variants (e. g. acidic and basic monomers), glycosylation variants, and/or soluble size variants (e. g. aggregates, monomers, ? fragments, ¾ fragments, antigen binding fragments (Fab) and crystallisable fragments (Fc).

Abstract: Disclosed are improved preparative (>5 g/l) protein separations, which are achieved by combining salt and pH gradients for preparative protein separations in combination with the development of a preparative step elution protein separation based on data generated by combined salt-pH gradient runs.

Abstract: The present invention relates to the purification of target molecules like immunoglobulins from plasma. The use of a certain type of ion exchanger based on a crosslinked polyvinylether results in especially high yields of the target molecule.

Abstract: The present invention relates to a process for the production of the largest possible spherical, monodisperse polyvinylpyrrolidone (PVP) seed particles in the micron range by dispersion polymerisation. The particles obtained in this way represent novel starting materials for the production of macroporous polymer particles, which can in turn be employed in preparative and analytical chromatography for protein preparation. They can also be employed as base material for further reactions. The novel process for the polymerisation of N-vinylpyrrolidone, which is inexpensive to carry out, gives particles having optimised quantities, such as monodispersity, sphericity and particle diameter, which can be employed in further reactions and have advantageous, in particular improved, properties for use in chromatographic separation methods.

Abstract: A microcomponent connection system (1) having an accomodation device for plate-shaped microcomponents (7) has a connection block (2) and a lifting device (6), by means of which the microcomponent (7) and the connection block (2) can be pressed against one another. The connection block (2) has electrical and fluid line connections (8, 9) and optical line connections (16), each of which projects in a sprung or spring-mounted manner on the underside of the connection block (2). In order to connect the microcomponent (7) to the associated line connections (8, 9, 16), the microcomponent (7) is pressed by the lifting device (6) in the direction of the connection block (2) against the electrical line connections (8) or fluid line connections (9) designed as electrically conducting spring tongues or as hollow rams (10), or optical line connections (16).

Abstract: The invention relates to a method for linking two adjacent plastic work pieces (2, 3). The inventive method is characterized in that the intended contact zone (K) of at least one of the two work pieces (2) with which the latter adjoins to the other work piece (3) is at least partially subjected to a high-energy radiation to such an extent that the glass transition temperature is reduced in a marginal zone (R). The two work pieces (2, 3) are brought in the desired position relative to each other. For establishing the connection of the two work pieces (2, 3) at least the marginal zone (R) modified by the previous radiation process is heated at least in its surface area to a temperature that is higher than the glass transition temperature of the marginal zone (R) modified by the radiation process but lower than the glass transition temperature of the zones of the work pieces (2, 3) that have not been modified.
