Abstract: The present disclosure relates to novel bis-maleic anhydrides and to the surprising discovery that bis-maleic anhydride cross-linking agents can be used for preservation/fixation of a cell or tissue sample. Various bis-maleic anhydride cross-linking agent scan be used in methods requiring fixation of a cell or tissue sample. These reagents and methods are especially useful in procedures that require that the fixation agent be removed in order to facilitate analysis with other reagents. The inventive reagents and methods make it easier to reliably assay for various proteins, a nucleic acid and the like using analytical methods such as like immunohistochemistry, fluorescence in situ hybridization, RT-PCR, and the like.

Abstract: The invention relates to a process for the production of a biomolecule-linker conjugate of uniform stochiometry. It especially relates to a conjugate consisting of a biomolecule of a molecular weight between 5 kD and 500 kD and a hydrophilic linker molecule said linker having a molecular weight between 1 and 15 kD and between 4 and 60 charged residues, characterized in that said conjugate comprises at least one biomolecule-linker product of uniform stoichiometry in a pre-selected amount.

Abstract: The present invention relates to a reagent for digestion of hemoglobin comprising a buffer, pepsin and a 1,3-dialkyl-imidazolium salt. It also discloses to the use of this reagent in a method for digesting hemoglobin, in a method for detecting HbA1c, and to a sampling tube for collection of a whole blood sample comprising said reagent for digesting hemoglobin.

Abstract: The invention relates to a modular microelectronic-system comprising: a first connection module (12) which can be firmly connected to user interface devices integrated textile material; and a second connection module (14) which comprises user interface devices (24, 26) and/or which an be connected to an external device; in addition to an electronic module (10) which can be connected to the first connection module (12) or to the second connection module (14).

Abstract: The invention concerns processes for producing modified oxidic nanoparticles with hydrophobic inclusions, in particular metal oxide particles which contain halogen-containing target molecules; the particles produced in this manner and the use thereof especially as a toner, sunscreen agent, insecticide or for labelling biomolecules.

Abstract: The present invention concerns new fluorescent dye systems especially for fluorescence resonance energy transfer determinations for example combined with the time-resolved measurement of the resulting fluorescence. The invention also concerns the use of these dyes to label biomolecules and for the homogeneous determination of interactions between biomolecules, for example for detecting an analyte.
