Development and validation of monoclonal antibodies specific for Candida albicans Als2, Als9-1, and Als9-2.

ABSTRACT: Fungal agglutinin-like sequence (Als) cell-surface glycoproteins, best characterized in Candida albicans, mediate adhesive and aggregative interactions with host cells, other microbes, and abiotic surfaces. Monoclonal antibodies (MAbs) specific for each C. albicans Als protein are valuable reagents for gaining insight into Als protein localization and function. This manuscript describes development and validation of MAbs specific for C. albicans Als2, as well as for C. albicans Als9-1 and Als9-2, two protein variants produced from the ALS9 locus. Native C. albicans ALS9 expression levels were not sufficiently high to produce detectable Als9 protein on the wild-type cell surface so MAb validation required production of overexpression strains, each featuring one of the two ALS9 alleles.
