Fungicidal monoclonal antibody C7 binds to Candida albicans Als3

Monoclonal antibody (MAb) C7 reacted with a > 200-kDa component from the Candida albicans cell wall identified by matrix-assisted laser desorption ionization-time-of-flight mass spectrometry as Als3. It also bound the recombinant N terminus of Als3. Binding of MAb C7 to Als3 may explain the biological activities exerted by the MAb on C. albicans.
