Description

technical field [0001] The invention relates to the field of medical diagnostic reagents, in particular to a magnetic particle chemiluminescence detection kit for detecting human Golgi body protein content using magnetic particle chemiluminescence technology and antigen-antibody combination technology. Background technique [0002] Golgi protein (GP73) is a transmembrane Golgi glycoprotein including 400 amino acid residues, located in the 9q21.33 chromosome genome, also known as GOLM1 or GOLPH2. GP73 is composed of inner and outer C-terminals and hydrophobic N-3, and has a complete transmembrane structure. In normal people, GP73 is only expressed in gallbladder epithelial cells, almost not expressed in liver cells, but has a higher expression level in bile duct epithelial cells. When the liver is inflamed, the level of GP73 in liver cells increases, and the expression level of GP73 in liver cancer cells increases significantly. Relevant data show that the regulation mechan...
