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 Tissue and Bacteria Kit provides the components and procedures necessary for purifying genomic DNA from animal tissue and bacteria cells. Notice that, DNJia Tissue and Bacteria 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 ROJE Technologies

Quality Control

DNJia Tissue and Bacteria 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 ROJE Technologies


DNJia Tissue and Bacteria Kit is designed for isolating DNA from up to 25 mg tissue sample or up to 2 x 109 bacteria cells. Lysis is achieved by incubation of the sample in a RJ-Protease enzyme solution and TLB.  Appropriate conditions for DNA binding to the silica membrane is achieved by the addition of chaotropic salts and Ethanol to the lysate. Then, DNA is selectively bound to the membrane. Contaminants are removed by two specific washing buffers. Pure genomic 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
  • Micro centrifuge
  • Dry Heat Block/ Water Bath


The isolated DNA can be used in many downstream applications:

  • Different kinds of PCRs, including Long-range PCR
  • Sequencing
  • Restriction digestion
  • Southern blotting
  • Cloning
