Abstract

The invention relates to an immunonephelometry kit for detecting lipid carrier protein related to neutrophils gelatinase and a preparation method thereof; an application liquid bottle, an antibody suspending liquid bottle and a standard substance bottle are placed in a box body; application liquid is arranged in the application liquid bottle, and comprises the following components of: 0.01 percent to 1 percent of surfactant, 0.01 percent to 0.5 percent of preservative, 1 percent to 20 percent of sodium chloride and 20mmol/l to 200mmol/l of buffer solution; the antibody suspending liquid bottle contains emulsion suspension which is coated with the monoclonal antibody of the lipid carrier protein related to the neutrophils gelatinase, and the emulsion suspension has the following components of: 0.05 percent to 0.5 percent of emulsion which is coated with the monoclonal antibody of the lipid carrier protein related to the neutrophils gelatinase, 0.01 percent to 1 percent of surfactant, 0.01 percent to 0.5 percent of preservative and 20mmol/l to 200mmol/l of buffer solution; and the standard substance bottle contains the standard substances of the lipid carrier protein related to the neutrophils gelatinase. According to the invention, the mass quantitative detection on a biochemical instrument is realized.

Description

technical field [0001] The invention relates to an immunoturbidimetric detection method, in particular to an immunoturbidimetric kit for detecting neutrophil gelatinase-associated lipocalin and a preparation method thereof. Background technique [0002] Neutrophil gelatinase-associated lipocalin rapid detection ELISA kit can be used for human urine, plasma and serum detection. Acute renal failure (ARF) is a common complication of cardiac surgery, nephrotoxicity, and kidney transplantation. [0003] Neutrophil gelatinase-associated lipocalin (neutrophil gelatinase-associated lipocalin, NGAL), also known as Lipocalin-2 (lipocalin-2), is a new member of the lipocalin family, is the Early biomarkers of injury. NGAL not only exists in neutrophils, but also in specific epithelial cells. For example, in the process of ischemic and toxic renal injury, NGAL in renal tubular epithelial cells will increase significantly. Within hours, the levels of NGAL in urine and blood will incre...
