  • Patent number: 6713264
    Abstract: The process is used for the screening of molecules from molecule libraries with regard to their individual binding behavior towards at least one given ligand. For this purpose the ligands labelled with a fluorescent dye are mixed with the molecule library which is in the form of a suspension. The mixture is plated out on a two-dimensional substrate (2) after the excess, unbound ligands have been washed out. Then the local fluorescence intensities on the substrate are electro-optically identified in a fluorescence microscope (5) and electronically discriminated in accordance with given selection criteria. The objects selected and localised in this way are then sequentially positioned exactly by a displacement, the coordinates of which are controlled by the image calculator, between the substrate (2) and a separation actuator (20, 21) and are spatially separated from the substrate (2) by the separation actuator (20, 21).
    Type: Grant

  • Patent number: 5324786
    Abstract: The invention provides a method for the production of a solid phase system of the formula F--(--R.sup.3 --Y--CO--CR.sup.2 .dbd.CR.sup.1 --CH.sub.2 --X).sub.m using new allyl esters of the formula:X--CH.sub.2 --CR.sup.1 .dbd.CR.sup.2 --CO--Y--R.sup.3 --A (I).R.sup.1 and R.sup.2 are hydrogen, halogen, alkyl or aryl, R.sup.3 is a spacer, X is acyloxy where acyl is the residue of an aliphatic carboxylic acid or is RCO-- in which R is an organic group. Y is oxygen or sulphur or an --NH-- group and A is a grouping which can react with a solid carrier material F, which contains functional groups B. A and B are groups which react with one another with condensation and/or addition and formation of a linkage between the solid carrier material and X--CH.sub.2 --CR.sup.1 .dbd.CR.sup.2 --CO--Y--R.sup.3 --.

  • Patent number: 5214195
    Abstract: The present invention provides new allyl esters of the general formula:X--CH.sub.2 --CR.sup.1 .dbd.CR.sup.2 --CO--Y--R.sup.3 --A (I)wherein R.sup.1 and R.sup.2, which can be the same or different, are hydrn or halogen atoms or alkyl or aryl radicals, R.sup.3 is a linking grouping (spacer), X is an acyloxy radical in which acyl in the acyloxy radical is the residue of an aliphatic carboxylic acid or is the radical RCO-- in which R is an organic radical, Y is an oxygen or sulphur atom or especially an --NH-- group and A is a grouping which can react with a solid carrier material F, which contains appropriate functional groups B, either after selective deblocking or directly, whereby A and B are atom groupings which react with one another with condensation and/or addition and formation of a linkage between the solid carrier material and the radical X--CH.sub.2 --CR.sup.1 .dbd.CR.sup.2 --CO--Y--R.sup.3 --.The present invention also provides processes for the preparation of these new allyl esters.
