HDAOS Powder

Application:This product can be used in the water-soluble reagent for the determination of hydrogen peroxid e by enzyme photometry, widely used in diagnosis and biochemical test.

Total cholesterol (TC) includes free cholesterol (FC) and cholesterol ester (CE) and can be determined by more than a hundred different methods, which can be divided into five main categories: chemical reagent colourimetric methods, enzymatic methods, fluorescence methods, gas phase and high performance liquid chromatography. Due to the high conditions of gas phase and high performance liquid chromatography, enzymatic determination of total cholesterol using chromogenic substrates such as HDAOS is currently the most routinely applied method, with the advantages of rapidity, accuracy, specificity, low sample volume, no need for extraction and ease of automated analysis and batch determination.

Cholesterol is also known as cholesterol. It is a derivative of cyclopentan e polyhydrophenanthrene. Cholesteryl esters in serum are hydrolysed by the enzyme cholesteryl esterase CHE to free cholesterol and free fatty acids (FFA). Cholesterol is oxidised by the enzyme cholesteryl oxidase CHO to produce 4- cholestenone and hydrogen peroxid e. In the presence of peroxidase, the generated hydrogen peroxid e oxidises the chromogenic substrate HDAOS coupled to 4-AAP to produce a red quinonimine, the absorbance of which is measured by spectrophotometer and is proportional to the TC content of the subject.
The reagents required for the assay of total cholesterol are: pH buffer 50 mmol/L at pH 6.7, cholesterol esterase ≥ 200 U/L, cholesterol oxidase ≥ 100 U/L, peroxidase ≥ 3000 U/L, 4-AAP 0.3 mmol/L, HDAOS 5 mmol/L and also a cholesterol standard solution of approximately 5 mmoL/L. Serum TC concentration Equal to the assay tube to standard absorbance ratio multiplied by the concentration of the cholesterol standard solution.

It is important to note that the quality of the enzyme in the reagent affects the result; if the free cholesterol concentration is to be measured, the cholesterol esterase can be removed from the enzyme reagent; the test specimen can be serum or plasma (anticoagulated with EDTA dipotassium or heparin). Serum TC reference values: 3.0-5.20 mmol/L; risk threshold: 5.20-6.20 mmol/L; hypercholesterolaemia: ≥6.20 mmol/L.

In the detection of total serum cholesterol, the chromogenic substrates HDAOS, HRP or POD and the enzymatic preparations cholesterol esterase and cholesterol oxidase are all indispensable reagent raw materials, and as an old reagent manufacturer, De Sheng can provide a wide range of reagent raw materials including these.
