Abstract: The present invention relates to a method for preparation of a 2-chloro-1,10-phenanthrolinamine, comprising the steps: i) conversion of a 2-chloro-1,10-phenanthroline to a 2-chloro-nitro-1,10-phenanthroline characterized by a formula 2, j) hydrogenation of said 2-chloro-nitro-1,10-phenanthroline characterized by formula 5 to a 2-chloro-1,10-phenanthrolinaminecharacterized by formula 3. The present invention relates further to a method for preparation of a 2-[2-[bis(carboxymethyl)amino]ethyl-[2-[carboxymethyl-[2-[4-[2-(isothiocyanato-1,10-phenanthrolin-2-yl)ethynyl]anilino]-2-oxo-ethyl]amino]ethyl]amino]acetic acidcharacterized by formula 7 and a method for quantifying a biomolecule in a sample.

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: The invention relates to a method for the detection of an analyte containing polyamino acid. The object of the invention is to detect polyamino acids in a highly sensitive manner. The object is achieved in that an LM is coupled to a protein after chemical activation, and is complexed using a lanthanoid ion. In order to detect polyamino acids, the time resolved fluorescence measurement is utilized after electrophoretic separation. The detection limit is 0.5 pg per spot (bovine serum albumin), wherein the linear region extends across six orders of magnitude. The invention also relates to analytes containing nucleic acid.
