Ready-to-use ELISA kits are available for the detection of galactose-4-epimerase, UDP, an alias of the protein, UDP-galactose-4-epimerase. The official gene symbol is GALE. The protein has a mass of 38.3 kDa and length of 348 residues. It is a member of the NAD(P)-dependent epimerase/dehydratase family and may be known by other names, including: galactose-4-epimerase UDP-, UDP-N-acetylglucosamine 4-epimerase, UDP-GlcNAc 4-epimerase, UDP-GalNAc 4-epimerase, UDP galactose-4'-epimerase, and UDP-glucose 4-epimerase.
