摘要:
Provided is a method for separating two or more analytes in a fluid, which method comprises: (a) binding each different analyte to a different functional particle in one or more binding zones, to produce two or more bound analytes; (b) allowing the bound analytes to move through a separating conduit to two or more separate functional zones; wherein, each different functional particle has, or can be controlled to have, a different function in the fluid as compared with the other functional particles; and wherein the separating conduit separates into two or more functional conduits, such that the separating conduit serves to separate the bound analytes into the separate functional conduits by means of the different functions of the different functional particles. Also provided is an apparatus for separating two or more analytes in a fluid, which apparatus comprises: (a) a binding zone; (b) two or more functional conduits; (c) a separating conduit connecting the binding zone to the two or more functional conduits; (d) a transporter for transporting the analyte through the separating conduit from the binding zone to the two or more functional conduits; and (e) optionally one or more concentrating zones in connection with at least one of the functional conduits.
摘要:
The present invention relates to method for assaying anti-cyclic citrullinated peptide antibodies in a clinical sample, said method comprising contacting said sample with at least one homogeneous reagent comprising at least one specific binder for anti-CCP antibodies, whereby to form a solution or suspension of an anti-CCP-binding partner complex in a homogeneous sample mixture and detecting the presence or level of said anti-CCP-binding partner complex in a homogeneous liquid-phase. The invention also relates to a method for the assessment of the existence of; risk of; potential for; or propensity to RA in a subject.

The invention relates to a method for assaying homocysteine in a sample such as blood, plasma or urine, which comprises the steps of contacting the sample with a homocysteine converting enzyme and at least one substrate for the enzyme other than homocysteine, and without chromatographic separation, assessing a non-labelled analyte selected from a homocysteine co-substrate and the homocysteine conversion products of the enzymic conversion of homocysteine by said enzyme.

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 assay methods for the determination of cobalamin or vitamin B12 in a body fluid and in particular to assay methods for the metabolically active pool of cobalamin, comprising contacting a cell free sample of a body fluid with an immobilised or immobilizable specific binding ligand for TC II or holo TC II, separating a ligand bound fraction from a non-ligand bound fraction and measuring the holo-TC II or TC-II bound cobalamin content therein.

The invention relates to a method for assaying homocysteine in a sample such as blood, plasma or urine, which comprises the steps of contacting the sample with a homocystene conveying enzyme and at least one substrate for the enzyme other than homocysteine, and without chromatographic separation, assessing a non-labelled analyte selected from a homotysteine co-substrate and the homocysteine conversion products of the enzymic conversion of homocysteine by said enzyme.
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:
A method of assessin glycated blood protein in a sample which comprises separating glycated and non-glycated protein using a liquid phase precipitation reagent, contacting the sample before or during the separation with a signal forming agent capable of binding preferentially to the glycated protein, and assessing the signal forming agents.
摘要:
An assay method for the detection of potential for CVD or propensity to CVD in a human or non-human animal subject, said method comprising assessing the concentration of calprotectin in a calprotectin-containing sample taken from said subject.
