Preparation and use of monoclonal antibodies to detect Phytophthora nicotianae var. nicotianaeOriginal Paper
A monoclonal antibody (MAb 18) was prepared against purified mycelial proteins from Phytophthora nicotianae var. nicotianae. The specificity of MAb 18 (lgG class) was tested using indirect ELISA (PTA-ELISA).It cross-reacted with Phytophthora cacto rum, P. cinrzamomi, P. cryptogea, P. fragariae) but not with other fungi (Fusarium oxysporum, Pythium ultimwn and P. oligan drwn) and bacteria (Clavibacter michiganensis subsp. michiganensis) isolated from tomato. Phytophthora nicotianae var. nicotianae was detected in roots and basal stems of artificially infected young tomato plants using indirect ELISA and immunoprinting.
