Abstract: A method for the determination of the amount of cholesterol in high density lipoproteins in a high density lipoprotein containing sample, said method comprising reacting the sample with a surfactant which selectively reacts with high density lipoproteins in the sample, said surfactant being selected from sucrose esters, and maltosides, and measuring the amount of cholesterol in the high density lipoproteins, for example using an electrochemical technique.

Abstract: A method for the determination of the amount of cholesterol in high density lipoproteins in a high density lipoprotein containing sample, said method comprising reacting the sample with a surfactant which preferentially reacts with high density lipoproteins in the sample, said surfactant being selected from hydroxyethyl glucamide derivatives and N-acyl-N-methyl glucamine derivatives, and measuring the amount of cholesterol in the high density lipoproteins, for example using an electrochemical technique.

Abstract: The invention provides a method for manufacturing or preparing neutral, low molecular weight 99mTc-labeled and 186Re-labeled carbohydrate complexes with an improved radiochemical yield from a simple functionalized sugar, such as glucosamine. In particular the synthesis relies on single ligand transfer (SLT) or double ligand transfer (DLT) reactions for converting a ferrocene compound into a rhenium or technetium tricarbonyl complex. The ferrocene compound may be linked to a sugar through various functional groups including, for example, thio, amino and alcohol functionalities to provide a wide range of radiolabeled sugar complexes that include both water soluble and relatively water insoluble compounds.
