Ready-to-use ELISA kits are available for the detection of alpha-dystroglycan, an alias of the protein, dystroglycan 1. The official gene symbol is DAG1. The kits can detect several species variants of the protein, including: human, mouse, rat, chicken, primate, and guinea pig. The protein, with a mass of 97.4 kDa and length of 895 residues, is reported to be cytoplasmic, nuclear, membrane-associated and secreted. It may be known by other names, including: MDDGA9, LGMDR16, AGRNR, 156DAG, dystroglycan 1 (dystrophin-associated glycoprotein 1), and dystroglycan, and MDDGC9.
