Abstract: Novel chemical compounds, with application in fluorometric analytical methods, for qualitative and quantitative determination of biomolecules. The aim of the invention is to identify and prove the suitability of such compounds. Said aim is achieved with compounds of formula (1) where R1 is an antenna function, R2 is a chelate forming agent, containing a coordinated lanthanide(III)ion, X is —OH or a group with affinity for the biomolecule, bonded to a carboxylate group of the chelate forming agent by means of an amide bond and Y is —H or a group with affinity for the biomolecule, coupled to the antenna function.

Abstract: Plastic cable with at least one electric conductor which is surrounded by a cable covering which, besides an insulating layer comprises several electrically conducting layers of a polymer material. At least one electrically conducting layer is made of a polymer, a mixed polymerizate or a polymer alloy which is meltable and/or soluble, and the electric conductivity of which can be adjusted to a defined value by a content of charge transfer complexes.
