Abstract
A new laccase-conjugated antibody is developed, containing laccase as an enzyme marker, obtained from culture supernatant of the basidiomycetous fungi Pleurotus ostreatus. The efficacy of the laccase-conjugated antibody was demonstrated in indirect and direct enzyme immunoassay after using periodate and glutaraldehyde conjugation methods. The assay based on laccase-conjugated antibody is potent to detect antigens when compared with peroxidase conjugated antibody.
