Sensitive and Cost-Effective Immunocapture RT-PCR for Routinely Viral Detection in Large Number of Plant Samples. Phytopathology. 100-S139. Interpretive Summary: N/A Technical Abstract: It has long been a challenging task to develop timely and accurate diagnostic tests for diseases caused by viruses or virus-like agents in plants in agriculture production. Current ELISA detection methods may not provide the sensitivity needed for samples with low viral concentrations. Conventional RT-PCR, which requires relatively pure nucleic acid samples, is costly and time-consuming. By combining two widely used virus detection methods, ELISA and RT-PCR, Immunocapture RT-PCR was developed for practical detection of plant viruses. The immunocapture sample preparation allows RT-PCR to be performed in a 96-well format equivalent to that of a regular ELISA test. The entire RT-PCR assay, viral immunocapturing from samples, captured viral RNA amplification and amplicon detection, can be conducted in a single PCR reaction tube within a relatively short time. This novel technology makes it possible to routinely detect plant viruses in large number of samples by RT-PCR. This sensitive and cost-effective immunocapture RT-PCR assay has huge potential applications in plant viral disease diagnosis. |
