There are a number of ELISA Kits available for the measurement of mannosidase 1, alpha, another term for the human protein, mannosidase alpha class 1A member 1. Other synonyms may include: mannosyl-oligosaccharide 1,2-alpha-mannosidase IA, Man9-mannosidase, alpha-1,2-mannosidase IA, man(9)-alpha-mannosidase, HUMM3, HUMM9, and MAN9. It is encoded by the MAN1A1 gene to yield a protein 653 amino acids in length and 73 kDa in size. However, there are up to 2 reported isoforms. The protein, an enzyme, is categorized into the Glycosyl hydrolase 47 family. Versions of mannosidase 1, alpha are present in other organisms, including: Mouse, Rat, Zebrafish, Frog, Chicken.
