DNJia Blood & Cell Kit

 10,233,600 18,409,200

DNJia Blood & Cell Kit provides a rapid, careful, convenient and phenol-free method for high quality genomic DNA isolation from whole blood, buffy coat, body fluid, plasma, serum, animal cultured cell etc. The procedure is based on spin column technology, which takes less than 20 minutes. DNJia Blood & Cell Kit needs less handling and it is convenient for simultaneous isolation, which makes it favorites for laboratory with many isolations in a day. Typical yields of genomic DNA vary, depending on cell density of blood samples. The isolated DNA is ready to use in downstream applications such as PCR analysis and restriction endonuclease digestions.

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 Blood & Cell Kit provides the components and procedures necessary for purifying genomic DNA from whole blood, buffy coat, body fluid, plasma, serum, animal cultured cell etc. Notice that, DNJia Blood & Cell 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.com

Quality Control

DNJia Blood & Cell 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 Blood & Cell Kit is designed for isolating DNA from whole blood, buffy coat, body fluid, plasma, serum, animal cultured cell 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 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

Recommended Starting Material

The size of recommended starting material to use with determined lysis volume are listed here.

Table 2: Recommended starting material and Lysis Buffer amount

Sample Size of Starting Material Lysis Buffer Amount
Blood* Up to 250 µl 250 µl
Buffy coat Up to 200 µl 300 µl
Cultured cell ≤5 x 106 cells 250 µl

*White Blood Cell counts are extremely variable from a person to person and therefore, for optimum results its recommended to determine cell counts for choosing the best protocol for purification. For healthy individuals, white blood cell counts normally from 4-10 million per 1 ml blood; however, depending on disease state, cell counts may be higher or lower than the normal range.
