Product Overview
This rabbit polyclonal antibody targets golgi membrane protein 1 (gene Golm1) in mouse and rat samples and is validated for Western blot, IHC, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 44.3 kDa, and the supplier reports an observed band at about 73 kDa.
Golgi membrane protein 1 (GOLM1, also called GP73) is a type II transmembrane protein located in the cis-Golgi. Its expression rises in response to viral infection and in several liver conditions, and it has been studied as a serum marker in liver disease research, though its normal function is not fully understood.
