Alternatively, the detection of other antigen such as tegumental antigen at MW28.5 kDa could also be used together with the MoAb against CatB3, since the 28.5 kDa TA was proven to be present and released from the adult stage of F. gigantica and its exploit in immunodiagnosis by sandwich ELISA has already been published by our group (Anuracpreeda et al., 2009b).
