Abstract: Diagnostic methods for in vivo and ex vivo detection of circulating tumor cells (CTCs) for the diagnosis and treatment of cancer are provided. The diagnostic methods employ oncolytic viruses alone or in combination with one or more tumor cell enrichment and/or detection methods. Combinations and kits for use in the practicing the methods also are provided.

Abstract: A separation device and a separation method for biomolecular sample material and in particular protein mixtures. For this purpose a separation element 10 for the two-dimensional and preferable electrophoretic separation of components of the sample material is provided in area 30 of a separation plane. According to the invention it is proposed that the separation element 10 has a channel or transfer structure 14 for the locally resolved discharge of separated sample components in a transport direction that is at right angles to the separation plane onto a support surface 16 that is preferably suitable for mass spectroscopic analyses.

Abstract: The present invention concerns a matrix reactor for reactions in which low-molecular and high-molecular reactants are involved wherein the reactor space VR contains a matrix and comprises a reaction compartment and a supply compartment, wherein the matrix is composed of a porous material which can take up low-molecular reactants and wherein the exclusion volume V0 of the matrix is available as the reaction compartment and the matrix volume VM of the matrix is available as the supply compartment. The matrix reactor can be used for enzymatic processes, in particular for a coupled in vitro transcription/translation reaction to produce proteins.

Abstract: The present invention concerns a method for producing linear DNA fragments for the in vitro expression of proteins in which a linear DNA fragment which contains control elements necessary for expression and the protein-coding gene which has complementary regions to the two ends of the linear DNA fragment at both ends, are amplified together using a primer pair which binds upstream and downstream of the expression control regions on the linear DNA fragment, characterized in that the linear DNA fragment can be produced by linearizing an expression vector. Furthermore a method is disclosed which concerns the preparation of the protein-coding gene the ends of which have regions which overlap the linear DNA fragment.
