    • The present invention provides a method of assessment of the concentration of a subset of variants in a population of proteinaceous analyte variants capable of separation by a fractionation system, wherein said population of variants are contacted with a population of labelled proteinaceous specific binding partners therefor to form labelled binding partner-analyte complexes therewith, which are then subjected to separation by the said fractionation system into one or more fractions containing said subset of analyte variants in complexed form and assessment of the amount of label in one or more fractions so obtained, the said population of specific binding partners having, prior to reaction, substantially uniform distribution or mobility in said fractionation system, compositions and test kits for use in such methods. The method of the invention is particularly suitable for the analysis of variants of the protein transferrin.

    • A method of assessing glycosylated haemoglobin in a sample, wherein the method comprises the steps of (a) contacting the sample with signal-forming molecules comprising a conjugate of one or more dihydroxyboryl residues or salts thereof, linked to a signal-forming label; (b) separating by selective precipitation from a homogenous solution, glycosylated and non-glycosylated haemoglobin and any molecules bound thereto, from the reaction mixture of step (a) above; and (c) assessing signal-forming molecules selected from the group consisting of signal-forming molecules which have bound to the separated haemoglobin, and non-haemoglobin bound signal-forming molecules. Steps (a) and (b) may be performed simultaneously or sequentially. The sample may optionally be haemolyzed to liberate any cell bound haemoglobin. The invention also comprises an analytical test kit for use in accordance with the method of the invention. The new assay of the invention is particularly useful for the in vitro diagnosis and monitoring of diabetes mellitus.
