Bluetongue virus (BTV) total genomic and isolated individual segment dsRNAs end-labeled with 32P were successfully used as probes in colony hybridization to detect clones of BTV genomic material. The RNA probes were highly specific for cloned BTV genomic material. DNA probes, however, gave false positive results. DNA from bacterial clones was fixed to nylon and nitrocellulose membranes. The hybridized nylon membranes could be stripped of probe and reprobed at least 6 times without loss of signal strength.
