Mouse anti Rhizopus arrhizus antibody, clone WSSA-RA-1 recognizes Rhizopus arrhizus and other members of the family Mucoraceae including Absidia corymbifera and Rhizomucor pusillus, reacting strongly with the cytoplasm of hyphae and also possibly with the walls and septae, where present.

R. arrhizus, an angio-invasive filamentous fungus, is one of the main causative agents of systemic bovine and human zygomycosis, a worldwide and often fatal respiratory disease. Clone WSSA-RA-1 has been successfully used in immunohistochemistry for the specific and consistent in situ diagnosis of systemic bovine zygomycosis, attributed to its possible binding to a highly glycosylated moiety on non-structural components.

Clone WSSA-RA-1 does not bind to water-soluble somatic antigens (WSSA) of Aspergillus spp.
