Positive Controls

Armored RNA (AR) is a good candidate for creating nuclease-resistant RNA positive controls in the nucleic acid - based assay for RNA viruses. To simplify the production and purifcation of armored RNA, a single plasmid double – expressing His6-tag system was designed. His-tag armored RNA particles were purifed using his-tag affnity. A genomic fragment of the zika virus consisting of the encoding sequences of flavi-M, flavi-E-C protein targeted for zika virus was selected to prepare a positive control. In this study, we have successfully produced His-taged MS2- phage like particles carrying specifc genomic regions (M and E genes) to monitor the procedures of real-time Reverse transcription-PCR for Zika virus detection in one plasmid double expression. AR-ZIKA is completely resistant to DNase and RNase, stable in normal human EDTA plasma at room temperature for at least 60 and 15 days at 40C and room temperature respectively.

A Current

Gene probes offer a rapid and sensitive method for the detection of viruses in water and other environmental samples. Gene probes are small strands of nucleic acid labeled with radioactive or nonradioactive compounds for their detection. The target organism is identified by the hybridization of the probe to the organism's nucleic acid. Nucleic acid probes are at least 1000-fold more sensitive than serological tests such as enzyme-linked-immunoassay and do not first require cultivation of the virus for detection. Gene probes have been developed for organisms that do not grow in cell culture, and probes have been constructed for most of the major groups of enteric viruses. Gene probes have been applied to the detection of enteric viruses in water, marine sediment and shellfish. Radioactively labeled probes can detect as little as 1-10 infectious units of virus within 48 hours. A current disadvantage of probes is that they cannot determine the infectivity of the viruses; however, they can be used to quickly determine the growth of viruses in cell culture. Further development of nonradioactive probes should place virus detection capabilities into the hands of most water quality laboratories.
