Only the Avidin- Biotin Penicillinase amplification technique was able to detect viruses in one single leafhopper. In the EMSA or gel shift assay, nucleic acid-binding proteins are detectable because they cause a change in the migration rate of labeled probes during electrophoresis through a gel matrix. The bond formation between biotin and Avidin is very rapid, and once formed, is unaffected by extremes of pH, temperature, organic solvents and other denaturing agents.
