摘要:
The present invention relates to a sensor with a novel construction for a detection method of molecules labelled with fluorescent dye for detecting these dissolved substances or analytes by energy transfer with a simple fluorescence technique and increased sensitivity in the detection as well as versatile use for different tasks and the possibility of reproducible preparation of films bound to solid surfaces.
摘要:
The present invention relates to polymer dyestuffs, i.e. polymer-bound dyestuffs, to a process for their preparation and to their use, for example as markers in analytical procedures. Polymer dyestuffs contain linkable functional groups and are water-soluble under customary conditions of analysis. The polymer portion is usually responsible for this water solubility. The dyestuffs per se are often water-insoluble.
摘要:
A polymer-bound linkable dye comprisinga) a water-soluble polymer backbone,b) a dye covalently bound thereto, andc) functional groups which enable the polymer-dye to link covalently with biological materials,in which the water-soluble polymer backbone is a copolymer which contains arcylamide, methacrylamide, N-C.sub.1 -C.sub.4 alkyl(meth)acrylamide, N,N-C.sub.1 -C.sub.4 dialkylacrylamide, N-vinylpyrrolidone, N-vinylpiperidone, N-vinylcaprolactam, N-vinylformamide, N-vinylacetamide, N-vinyl-N-methylacetamide, N-vinyl-O-methylurethane, ethene or vinylmethylether as nonionic monomer blocks. The polymer-bound dye can be linked to a biologically active material such as an antibody or nucleic acid and used analytically.

The present invention is directed to pure polyurethanes which are biocompatible. These pure polyurethanes comprise the reaction product of:a) a pre-adduct containing NCO groups and comprising the reaction product ofi) a diisocyanate selected from the group consisting of aliphatic diisocyanates, cycloaliphatic diisocyanates, and mixtures thereof, withii) a macrodiol having a molecular weight of from 500 to 10,000 wherein said components i) and ii) reacted at temperatures of from 90.degree.-150.degree. C.; withb) a chain extender having a molecular weight of from 62 to 400 and being selected from the group consisting of aliphatic diols, cycloaliphatic diols, and mixtures thereof, and optionally,c) additional diisocyanate selected from the group consisting of aliphatic diisocyanates, cycloaliphatic diisocyanates, and mixtures thereof,wherein said component c), when added, is added either simultaneously with component b) or separately from component b), the quantities of components a)i), a)ii), and c) being such that the molar ratio of diisocyanate to macrodiol is from 1.5:1 to 22:1, and the reaction of components a) and b) and optionally component c) is conducted at temperatures of from 90.degree. to 230.degree. C., with the proviso that the reaction conditions are maintained until said polyurethane has a melt viscosity of at least 2500 mPa.s at 120.degree. C.

摘要:
The present invention relates to new chromogenic amino acid esters and peptide esters of hydroxybenzo(iso)thiazoles and hydroxybenzopyrazoles and the use of the new esters as substrates for the analytical detection of esterolytic and/or proteolytic enzymes, for example in body fluids, the esters being incorporated into test agents, in particular test strips, in a suitable manner. The new esters are preferably used for the detection of leukocytes, in particular in urine.
