Anti-monoacylglycerol lipase antibodies enable researchers to detect and measure the monoacylglycerol lipase antigen in biological samples. This target is a reported synonym of the MGLL gene, which encodes monoglyceride lipase. This protein is known to function in inflammatory response pathways and the metabolism of lipids, among other biological roles. The human version of monoacylglycerol lipase has a canonical amino acid length of 303 residues and a protein mass of 33.3 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the membrane and cytoplasm of cells and notably expressed in many tissues, such as the cerebral cortex and colon. Other names for this target antigen include HU-K5, HU-K5, and HUK5. Immunohistochemistry is the most common application for the monoacylglycerol lipase antibodies listed below. ELISA, Flow Cytometry, Western Blot, and Immunofluorescence are also common applications.
