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

DNall Kit provides the components and procedures necessary for purifying genomic DNA from blood, buffy coat, body fluid, buccal cells, animal tissue, serum and plasma, fixed tissue, cultured cells and bacteria. Notice that, DNall Kit is intended for molecular biology applications not for diagnostic use.  We recommend all users to study DNA experiments guideline, before starting their work.


DNall Kit is designed for isolating DNA from various sample types. Lysis is achieved by incubation of the sample in a RJ-Protease enzyme solution and ROJE specific lysis buffer. 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.

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

DNall 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

Recommended Starting Material

To reach optimized results it is better to follow as listed here. The size of recommended material is written in Table 2.

Table 2: Appropriate size of starting material

SampleSize of Starting Material
Blood*Up to 250 µl
Buffy coatUp to 200 µl
Animal tissue All tissue kind expect spleen: up to 25 mg

(spleen up to 10 mg)

Bacteria cells2.5 x 10 8 to 2 x 109
Cultured cell≤5 x 106 cells

*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 1ml blood; however, depending on disease state, cell counts may be higher or lower than the normal range.
