“…Enzyme-linked fluorescent assay (ELFA) has the potential to be used as routine test for the detection of LMV and SMV in seeds. ELFA can detect LMV in a single infected seeds present in lots of 500 seeds and it was found to be 10 to 25 fold more sensitive than DAS-ELISA (Dolares-Talens et al, 1989). For the detection of SMV, ELFA proved to be more sensitive than standard ELISA format (Hill and Durand, 1986).Another sensitive detection technique is radioimmunoassay (RIA), using radioactive gamma globulin.…”
