Anti-MAN1B1 antibodies are used in the immunodetection of the protein mannosidase alpha class 1B member 1. In humans, the canonical protein has a reported length of 699 amino acid residues and a mass of 79.6 kDa. Its subcellular localization is in the ER. It is widely expressed across many tissue types. A member of the Glycosyl hydrolase 47 protein family, MAN1B1 is known to be involved in glycoprotein quality control targeting of misfolded glycoproteins for degradation. The MAN1B1 gene has been associated with the disease, Rafiq syndrome. Synonyms for this target antigen include ERManI, MANA-ER, MRT15, endoplasmic reticulum mannosyl-oligosaccharide 1,2-alpha-mannosidase, and ERMAN1. MAN1B1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of MAN1B1 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunocytochemistry, Immunofluorescence, and Immunohistochemistry are also common applications.
