Abstract

The invention provides an alpha fetoprotein variant 3 (AFP-L3) determination kit. The kit contains a reagent R1 and a reagent R2, wherein the reagent R1 contains the following components: a piperazine-1, 4-diethylsulfonic acid (PIPES) buffer solution, NaCl, a surfactant, a suspending aid and a preservative; and the reagent R2 is prepared from the piperazine-1, 4-diethylsulfonic acid (PIPES) buffersolution, goat anti-human AFP-L3 antibody coated latex particles, goat anti-human AFP-L3 antibody coated magnetic nanoparticles, the suspending aid, a stabilizer and the preservative. The invention also provides a preparation method and an application of the kit, and the kit can effectively replace a chemiluminescence immunoassay analyzer kit, is a novel liquid kit with strong stability, high sensitivity, good repeatability and low cost, and is convenient for clinical development and application of projects.

Description

technical field [0001] The present invention relates to the technical field of biochemical reagent determination, in particular to a kit for measuring alpha-fetoprotein heterogeneity 3, and also relates to a preparation method and application of the kit for determination of alpha-fetoprotein heterogeneity 3. Background technique [0002] Primary hepatocellular carcinoma (HCC) is one of the common malignant tumors in my country, with a high mortality rate, ranking third in the death order of malignant tumors after gastric cancer and esophageal cancer. my country is a big country with hepatitis B, and there are about 120 million cases of hepatitis B virus carriers. Every year, 130,000 patients die of liver cancer, accounting for 45% of the world's liver cancer deaths. Like other tumor screenings, the prevention and treatment of liver cancer mainly lies in the "three early", that is, early detection, early diagnosis and early treatment. Early liver cancer, if treated scientifi...
