Abstract: The invention relates to a method for manufacturing a concentrate enriched in iron mineral content from an ore, which contains an iron mineral and silicate, by a reverse flotation, which method comprises the step of (c) adding a collector composition comprising (i) an amidoamine, which contains a compound of formula I or a salt of a protonated compound of formula I and an anion, and (ii) an alkyl polyglycoside, which contains a compound of formula II wherein RAP is a linear or branched C6-C22 alkyl or a linear C6-C22 alkenyl, G1 is a monosaccharide residue having 5 or 6 carbon atoms, x is an average value from 1 to 10, to a prepared aqueous pulp of the ore and optionally one or more flotation auxiliary to obtain an aqueous mixture.

Abstract: The invention relates to a homogenous test system containing the following: (a) at least one or more, identical or different mobile nucleic acids with at least one spliceable nucleic acid, containing at least one intron; (b) at least two probes, containing corresponding fluorophores which preferably bind with the 5′ and/or 3′ ends of an exon/intron; (c) at least one gel-free detecting system for detecting a splicing reaction; and optionally (d) at least one composition containing splicing components; and (e) other auxiliary agents.

Abstract: The present invention relates to a test system comprising (a) one or more identical or different immobilized nucleic acid(s) having at least one spliceable nucleic acid, (b) at least one gel-free detection system for detecting a splicing reaction, where appropriate (c) at least one composition comprising splicing components, and preferably (d) suitable detection probes, and, where appropriate, (e) further aids.
