Abstract:An enzyme immunoassay has been developed that confirms identity and estimates cell numbers of Bradyrhizobium japonicum and Rhizobium leguminosarum bv. viciae in broth culture. Total testing time required is less than 10 min and no specialized equipment is required. The assay involves a simultaneous and brief reaction of cells, primary antibody, and secondary antibody -enzyme conjugate in aqueous suspension, after which the cells are captured on a 0.45-µm-pore-size syringe filter membrane. Upon addition of enzy… Show more
“…Currently, enzyme-linked immunosorbent assay (ELISA) is the most common immunological method for the identification and monitoring of rhizobia. Nonetheless, polyclonal antibody exhibited cross-reactivity with other rhizobial strains within the same species ( 6 ). This cross-reaction is a major concern for detection and monitoring of specific rhizobium by polyclonal antibodies.…”
Human scFv antibody generated from phage display technology was successfully used for the generation of specific recombinant antibodies: yiN92-1e10 and yiDOA9-162 for the detection of
Bradyrhizobium
strains SUTN9-2 and DOA9, respectively.
