Embodiment 1

[0061] Specifically, embodiment 1, a method for preparing glycated albumin calibrator and quality control product, comprises the following steps:

[0062] S1: Porcine serum processing and porcine serum albumin raw material preparation

[0063] S1.1: Take pig serum, use a high-speed centrifuge at 6000rpm-8000rpm, centrifuge for 20min-30min, discard the precipitate, and keep the supernatant;

[0064] S1.2: Take the centrifuged pig serum raw material, measure the volume accurately, slowly add solid ammonium sulfate, stir while adding, so that its saturation is 50%, after the addition, continue stirring for 15min-30min, until the ammonium sulfate is completely dissolved ;

[0065] S1.3: Use a high-speed centrifuge to centrifuge at 6000rpm-8000rpm for 20min-30min, discard the precipitate, and keep the supernatant;

[0066] S1.4: Use GE polysulfone membrane tangential flow ultrafiltration column to ultrafilter the supernatant after dialysis and centrifugation, control the concentr...

Embodiment 2

[0089] Specifically, embodiment 2, a method for preparing glycated albumin calibrator and quality control product, comprises the following steps:

[0090] S1: Porcine serum processing and porcine serum albumin raw material preparation

[0091] S1.1: Take pig serum, use a high-speed centrifuge at 7000rpm-9000rpm, centrifuge for 20min-30min, discard the precipitate, and keep the supernatant;

[0092] S1.2: Take the centrifuged pig serum raw material, measure the volume accurately, slowly add solid ammonium sulfate, and stir while adding, so that its saturation is 60%. After adding, continue to stir for 15-30 minutes until the ammonium sulfate is completely dissolved ;

[0093] S1.3: Use a high-speed centrifuge to centrifuge at 7000rpm-9000rpm for 20min-30min, discard the precipitate, and keep the supernatant;

Abstract

The invention relates to the technical field of biological medicines, and particularly discloses a method for preparing a glycated albumin calibrator and a glycated albumin quality control product, which comprises the following steps: treating porcine serum and preparing an albumin raw material; preparing a glycated albumin low-value quality control product; preparing high-value raw materials of a glycated albumin calibration product and a quality control product; adding a freeze-drying protective agent into the prepared glycated albumin calibrator and the quality control product, uniformly stirring, and sub-packaging and freeze-drying; and main performance index tests of accuracy and stability are carried out on the prepared product by using a corresponding experimental scheme. According to the method disclosed by the invention, the problems of high biological safety risk, low yield, poor stability, high cost and long production period of the original technical process are solved by utilizing a method of combining salting-out and ultrafiltration.

Description

technical field [0001] The invention relates to the technical field of biomedicine, in particular to a method for preparing a glycated albumin calibrator and a quality control product. Background technique [0002] Diabetes mellitus (DM) is a group of metabolic diseases characterized by hyperglycemia caused by defects in insulin secretion caused by genetic and environmental factors. Long-term hyperglycemia can lead to chronic damage and dysfunction of various tissues, especially the eyes, kidneys, heart, blood vessels, and nerves. Diabetic patients have typical symptoms of polyuria, polydipsia, polyphagia, and weight loss, and late complications can be fatal. In recent years, diabetes has an obvious upward trend in my country, and it has become the third most serious chronic disease that threatens health after tumor and cardiovascular disease. Diagnosis, treatment and monitoring of diabetes are of great significance to maintaining people's health. [0003] Glycated albumi...
