摘要: The invention provides novel labelled boronic acid conjugates of formula ##STR1## (wherein V is a reporter moiety; W.sup.2 is a bond or an organic linker moiety; W.sup.1 is a *SO.sub.2 NR.sup.2, *CONR.sup.2 or *CH.sub.2 N.sup..sym. R.sup.2.sub.2 group bound at the *-marked atom to the phenyl ring; R.sup.1 is hydrogen or an electron withdrawing substituent group; and each R.sup.2 independently is hydrogen or an optionally hydroxylated and optionally C.sub.1-6 -alkoxylated C.sub.1-6 -alkyl group) and salts thereof, e.g. for use in assays for cis-diols such as glycated blood proteins, having enhanced water-solubility and storage stability.

摘要: The present invention relates to labelling agents comprising non-proteinaceous boronic acid conjugates having absorption maxima at not less than 600 nm, said label being provided by e.g., an azine, triphenylmethane, cyanine or phthalocyanine dye. The labelling agents are useful in the estimation and quantification of cisdiols such as glycosylated haemoglobin, by virtue of the substantially total absence of overlap with the absorption spectrum of haemoglobin. Oxazine and thiazine dyes exhibiting similar absorption characteristics and containing other activated moieties are similarly useful labelling agents, especially in the presence of haemoglobin.

摘要: The present invention relates to a method of assaying for folate in a folate containing sample, wherein at least some of the folate comprises at least one attached glutamate residue. The method comprises subjecting the sample to hydrolysis to release paraminobenzoic acid, p-aminobenzoyl glutamic acid, or a salt thereof; contacting the released paraminobenzoic acid, p-aminobenzoyl glutamic acid, salt or a diazo derivative thereof, with a binding partner thereof; and directly or indirectly detecting the resulting binding partner: paraminobenzoic acid, binding partner: p-aminobenzoyl glutamic acid, or salt or derivative combination. The invention further relates to a kit usable in the method of the invention.
