  • Biospin Total RNA Extraction Kit II MORE
    Product Details:

    This kit is a column-type total RNA extraction kit based on the improved lysis and binding reagent components, which improves the lysis and binding performance of the reagent. The addition of chloroform realizes the separation of impurities such as RNA from DNA and protein, and optimizes the column membrane to improve its ability to adsorb RNA. After multiple washings, impurities are effectively removed to the greatest extent, and high-purity and high-quality total RNA is obtained. Nucleic acid can be extracted from a wide range of samples such as blood, animal and plant tissues, various microorganisms and cultured cells. High-quality nucleic acid products can be directly used in downstream molecular experiments such as Northern Blot, RT-qPCR, and NGS.

    Product Features:

    1.  High purity

    2.  No DNA residue

    3.  Sufficient protein removal

    4.  Simple operation

    lMeasure the OD using 100μl the RNA diluent solution, calculate the concentration of RNA as follows:

    Final concentration = (Spec reading A260) × (Dilution factor)  × (Conversion factor A260)

    ð The conversion factor for RNA is 0.040μg/μl per OD260 unit

    ð Notice: the range of Spec reading A2600.1≤OD260≤1.0

    Calculate the purity of RNA as follows: Ratio= (Spec.readingA260)/ (Spec.readingA280)

    ð Ration of 1.8~2.0 are considered ideal purity.

    The low pH will alter the OD measurements between 260 and 280nm, indicating a low purity.

    Introduction

        The kit provides a very simple, fast and effective technique for the isolation of pure high– molecular-weight genomic DNA in 10ml whole blood which was treated with anticoagulants such as citrate, heparin, EDTA. Based on the remarkable selectivity on genome DNA of Midispin membrane, the simple purification procedure involves only a few steps and allows isolation of high yields of pure genomic   DNA within 2hours. No any expensive equipment are required, using of toxic or hazardous reagents, such as phenol or chloroform is completely avoided. In general, 150~250μg genomic DNA can be acquired from 10ml blood using the Kit. The pure DNA can be applied extensively in PCR/Real-time PCR、sequencing、 Southern blot、mutant analysis、SNP, and so on.

    Product Features:

    Introduction

         This kit allows the high efficient binding of DNA to our spin matrix while proteins and  other  impurities are removed by wash buffer. Nucleic acids are easily eluted with sterile water or Elution Buffer. This kit is designed for fast and efficient purification of plasmid DNA from 150 to 200 ml of E. coli culture. The maxi column has a plasmid DNA binding capacity of 1 mg.

        The purified plasmid DNA is ready for downstream applications such as transfection of robust cells such as HEK293, restriction mapping, library screening, sequencing, as well as gene therapy and genetic vaccinations.

    Product Features:

    Storage and transportation

    •  The kit has demonstrated stability of 18 months when the RNase A should be stored at 2-8℃,others at room temperature.
    • The kit can be transported at room temperature.
    •  Resuspension Buffer should be stored at 2°C-8℃ once RNase A is added.

    Apparatus and materials to be prepared by the user

     *  50ml centrifuge tubes                            * 10µl/100µl/1000µl tips

     *  Centrifuge capable of 14,000g               * Absolute alcohol

    Important note

    1)Spin down RNase A vial briefly. Add the RNase A solution to Resuspension Buffer and mix well before use. Resuspension Buffer should be stored at 2°C-8℃ once RNase A is added.

    2)Wash Buffer: Add the alcohol as the volume marked on bottle label and mix well.

    3)Lysis Buffer precipitates below room temperature. It is critical to warm up the buffer at 50°C to dissolve the precipitates before use.

    4)Neutralization Buffer may form precipitates below 10°C, warm up at 37°C to dissolve the precipitates before use.

    5)Carry out all centrifugations at room temperature.

    6) Add 2ml Balance Buffer to each MaxiSpin column, incubate at room temperature for 2 mins,centrifuge at 5,000 x g for 3 min. Discard flow-through. It can improve the yield of DNA significantly.
