摘要:
The present invention provides a colorimetric process for the detection of an oxidative coupling reaction in which a coupling component is reacted with a developer component in the presence of an oxidation agent to give a colored material, wherein, as coupling component, there is used a compound of the general formula: ##STR1## in which X is a bromine or chlorine atom, n is 1, 2 or 3, Y is COOR, CONRR', SO.sub.3 R, SO.sub.2 NRR', OR, NRR' or NRR'R".sym. and R, R' and R", independently of one another, are hydrogen atoms or C.sub.1 -C.sub.3 -alkyl radicals.The present invention also provides a reagent which contains the above compound, as well as new substituted phenols and a process for the preparation thereof.
摘要:
The present invention relates to a reagent for digestion of hemoglobin comprising a buffer, pepsin and a 1,3-dialkyl-imidazolium salt. It also discloses to the use of this reagent in a method for digesting hemoglobin, in a method for detecting HbA1c, and to a sampling tube for collection of a whole blood sample comprising said reagent for digesting hemoglobin.
摘要:
This invention teaches a process for reducing protein matrix effects in assays for serum fructosamine. Blood or blood derived samples are used, and one adds two reagents, one of which reduces interference caused by non-specific reducing substances, the other of which eliminates turbidity. Incubation follows, and then the pH of the sample is adjusted and color forming reagent is added. In one embodiment, the incubation time is only 1-15 minutes. In another embodiment, the first reagent contains peroxidase.
摘要:
A process for the determination of fructosamine in body fluids by the reaction of a sample solution with a color reagent, wherein the sample liquid is mixed with a buffer solution having a pH value of from 9 to 12, a color-forming reagent and uricase, as well as with at least one detergent, and the chronological change of the extinction is measured kinetically in a temperature range of from 20.degree. to 40.degree. C. at the earliest after 5 minutes.

摘要:
Process for the specific determination of the serum fructosamine content in blood or in samples obtained from blood by reaction with an appropriate color reagent and measurement of the color change thereby brought about, in which before the color reaction sample components with a non-specific reducing action and/or causing turbidity are removed and subsequently the color reagent is added at a pH value of from 10 to 12. The sample components are removed by treatment at approximately neutral pH value with a reagent composition comprising at least one enzymatic oxidation agent, optionally together with peroxidase and/or catalase and/or lipase, as well as with at least one SH group-blocking substance. A kit for the specific determination of the serum fructosamine content in blood or samples obtained from blood, comprises said reagent composition, a rebuffering reagent with a buffer which has an alkaline pH value and a color reagent for the detection of fructosamine.
摘要:
For the determination of fructosamine in body fluids a solution containing fructosamine and albumin is used as the standard solution for calibration which standard solution is essentially free of glucose and which has a pH between 5.0 and 6.0 and contains at least 10 mmol/l buffer.
