Abstract

The invention relates to a detection kit for saccharifying serum albumin by using indirect immunifaction. The kit comprises a specificity monoclonal antibody which is prepared for a specific glycosylated area of the serum albumin and can be used for identifying the specific non-glycosylated glycosylated area with high degree of specificity. The kit also comprises a monoclonal antibody for specifically identifying a counterpoint area of the specific glycosylated area, and an immunonephelometry reagent is prepared by the specific monoclonal antibody and the monoclonal antibody. The concentration of albumin which does not take part in saccharifying reaction in the specific area is measured by identifying the specificity monoclonal antibody in the specific non-glycosylated glycosylated area, the concentration of the total albumin is measured by using the method in the prior art, and the concentration of the saccharified albumin can be obtained by subtracting the concentration of the total albumin by the concentration of the albumin which does not take part in the saccharifying reaction. The monoclonal antibody disclosed by the invention is easy to prepare and relatively low in cost, is not limited by the foreign patent, and is convenient to widely apply and popularize.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a detection kit for glycosylated serum albumin by an indirect immune method. Background technique [0002] Diabetes (diabetes) is a sugar, protein, A series of metabolic disorder syndromes including fat, water and electrolytes, clinically characterized by hyperglycemia, polyuria, polydipsia, polyphagia, weight loss, etc. Blood sugar) Once it is not well controlled, it will cause complications, leading to failure and lesions of the kidneys, eyes, feet and other parts, and it cannot be cured. [0003] At present, the routine clinical examination is to detect the blood glucose concentration of the patient, but the blood glucose measurement can only represent the immediate blood glucose level, and cannot show the change of the blood glucose concentration over a period of time, so it cannot be used as an indicator for evaluating the degree of disease control. [0004] Glucose in the blo...
