DNJia Virus DNA Kit


The DNJia Virus DNA Kit is designed for rapid and efficient purification of high-quality viral DNA from various human and animal liquid samples such as body fluid, plasma, serum etc. The kit utilizes a silica-based membrane technology in the form of a convenient spin column, which takes less than 30 minutes. DNJia Virus DNA Kit needs less handling and it is convenient for simultaneous isolation, which makes it favorites for laboratory with many isolations in a day. The purified viral nucleic acids are free of proteins, nucleases, and other contaminants or inhibitors of downstream applications. Isolated DNA can be directly used in PCR, qPCR or other nucleic acid-based assays.

Shipment condition is checked by ROJETechnologies. After arrival, all reagents should be kept dry, at room temperature. We suggested to store RJ-Protease at -20 °C for longer stability; However, for routine use it could be stored at 2-8 °C. When storage condition is as directed, all reagents are stable until expiration date, as indicated on the kit box.

Intended Use

DNJia Virus DNA Kit provides the components and procedures necessary for purifying viral DNA from cell-free samples such as body fluid, serum, plasma etc. Notice that, DNJia Virus DNA Kit is intended for molecular biology applications not for diagnostic use.  We recommend all users to study DNA experiments guideline, before starting their work.

Warning and Precautions

Due to chemical material usage that may be hazardous, always make sure to wear suitable lab coat, disposable gloves, and protective eyewear. Material Safety Data Sheet (MSDS) for all products and reagents are provided. They are accessible online at ROJETechnologies

Quality Control

DNJia Virus DNA Kit is tested against predetermined experiments on a lot-to-lot basis according to ROJETechnologies ISO-certified quality management system, to ensure consistent product quality. For your information, the results of all experiments are accessible by addressing Cat and Lot number on web at rojetechnoloes.com


DNJia Virus DNA Kit is designed for isolating DNA from body fluid, serum, plasma and etc. Lysis is achieved by incubation of the sample in a RJ-Protease enzyme solution and GLB. Appropriate conditions for DNA binding to the silica membrane is achieved by the addition of Ethanol to the lysate. Then, DNA is selectively bound to the membrane. Contaminants are removed by two specific washing buffers. Pure viral DNA is finally eluted in rehydration buffer. Isolated DNA is ready to use in downstream applications. It has A 260/A 280 ratios of 1.7-2, and a symmetric peak at 260 nm by spectrophotometer, confirms high purity.

Equipment & Reagents to be supplied by user

  • Ethanol (96-100%)
  • Pipets and pipet tips
  • 5 ml Microtube
  • Vortex
  • Centrifuge and Micro centrifuge
  • Dry Heat Block/ Water Bath


The isolated DNA can be used in many downstream applications:

  • Different kinds of PCRs
  • Restriction enzyme digestion
  • Viral genotyping
  • Viral detection
  • Viral load monitoring
