Provided below are ELISA kits targeting ALG12 alpha-1,6-mannosyltransferase, a human protein encoded by ALG12. This protein is 488 amino acids long, with a mass of 54.7 kDa, and is a member of the Glycosyltransferase 22 family. There is a noted implication in Congenital disorder of glycosylation 1G. Other alias names for this protein include: asparagine-linked glycosylation 12 homolog (S. cerevisiae alpha-1,6-mannosyltransferase), asparagine-linked glycosylation 12 alpha-1,6-mannosyltransferase homolog, dol-P-Man dependent alpha-1,6-mannosyltransferase, and dolichyl-P-Man:Man(7)GlcNAc(2)-PP-dolichol alpha-1,6-mannosyltransferase.
