| Abstract: | Expression condition for maximum recovery of recombinant Apple chlorotic leaf spot virus (ACLSV) coat protein was standardized. The in vitro expressed fusion protein with 6xHis tag (~43 Kd) was purified from inclusion bodies and used as an antigen for raising polyclonal antiserum in rabbit. This antiserum consistently detected ACLSV in pome and stone fruits as well as herbaceous host plants by direct double antibody sandwich enzyme linked immunosorbent assay (DAS-ELISA) and direct tissue blot immunoassay (DTBIA). The conditions for immuno-capture RT-PCR (IC-RT-PCR) were also standardized. |
