The 4-methylumbelliferyl-N-acetyl-beta-D-galactosaminide (UAG) test was evaluated in parallel with chlamydospore (CHL) and germ-tube (GT) tests for the identification of Candida spp. The UAG test gave 86.6% correct identification of C. albicans and C. tropicalis. Non-C. albicans and non-C. tropicalis yeasts

To evaluate a newly developed identification kit, the RID Zyme CAS test for Candida albicans, 1136 C. albicans and 403 non-albicans Candida strains were tested. Distinction of medically important non-albicans strains, with the exception of C. dubliniensis, was obtained. These

Rapid identification of Candida albicans is performed mainly by the germ-tube test. However, recent reports have suggested that up to 5% of C. albicans species can give false negative results. We describe the use of 4-Methylumbelliferyl N-acetyl-beta-D-galactosaminide (4-MAG) conjugate as

The number of carbohydrate-binding sites of the GalNAc-specific lectin is four per tetramer. The binding parameters of N-acetyl-D-galactosamine and methyl-N-acetyl-alpha-D- galactosaminide , were determined by titrating the perturbation in the absorption spectrum of the protein. For D-galactosides, it was necessary
