Spin type product which can extract high purity and yield total RNA without any genomic DNA contamination easily and quickly from cells and tissues

  • • A combination product of phenol solution and spin column
  • • Minimization of genomic DNA contamination
  • • High yield and high purity total RNA extraction
  • • Unnecessary of Alcohol PPT procedure because of using column to extract total RNA
  • • Highly reproducible results with the use of column
  • • RNA extraction within 30 minutes

easy-spin™ (DNA free) Total RNA Extraction Kit is designed to extract total RNA from cell and tissue in easy and fast way without mixing of genomic DNA. RNA extraction product is normally divided into column type and solution type. Solution type (phenol use) has higher yield comparing to spin type and also can extract large amount of RNA. Even though alcohol precipitation step is required due to the use of phenol, it has been widely used to extract RNA. On the contrary, spin type does not required alcohol precipitation to extract pure RNA, but it is mainly used for the rapid extraction of RNA from many samples, or for the safety and eco-friendliness of experimenters and the ease of experimentation.

As described above, the RNA extracted in the above two forms should have enough purity and yield to be used in almost all molecular biological experiments such as Northern blot analysis, cDNA synthesis and RT-PCR. It is a easy-spin™ (DNA free) Total RNA Extraction Kit that combines the advantages of the solution type and the column type. This product eliminates the inconvenience of the alcohol PPT stage when using the solution type product, and total RNA can be extracted within 30 minutes without contamination of genomic DNA. This product significantly reduces contamination concerns by using the CAPS method to individually pack the columns to effectively perform pathogen research (see Figure 1).

Technical Data

Comparison of extraction efficiency of total RNA according to various product groups

Total RNA was isolated and purified from SNU-1 cells using the easy-spin™ Total RNA Extraction Kit and competitors products; solution type and column type. In the case of extraction using the easy-spin™ Total RNA Extraction Kit, we could see that the extracted total RNA was superior to the total RNA extracted by the competitors products.

Results of genomic DNA contamination

We confirmed the presence of gDNA contamination by PCR amplification using IL-10 primer and total RNA extracted from easy-spin™ Total RNA Extraction Kit and competitors products; solution type and column type. In the case of the competitors products, gDNA contamination was confirmed in phenol type and column type, while we could confirm that gDNA contamination was negative in the RNA extracted by the easy-spin™ Total RNA Extraction Kit.

TroubleShooting Guide
QAfter transferring aqueous layer, can layer be separated after using binding buffer?
AAfter lysis, it is separated by centrifugation after chloroform treatment. After that, there is no layer separation phenomenon when the solution in the upper layer and the binding buffer are mixed. Therefore, all of the mixed solution should be loaded in the column.
QWhile using easy-spin kit, there is no enough lysis buffer. Can I purchase it separately?
Aeasy-spin Lysis Buffer is same as #17061 easy-BLUE.
QIs it possible to extract the RNA using the easy-spin kit and treat the isopropanol after storing it?
AIt is possible to store at refrigerator for one week. You do not need to add isopropanol because this kit is possible to store at refrigerator for one week.
