Universal Total RNA Extraction Kit (Small Volume) (Magnetic Bead Method)

【Product Introduction】

This universal total RNA extraction kit for small volumes is designed for the rapid extraction of total RNA from a wide range of tissue samples, including fresh plant, animal, fungal and cellular materials. The entire process is straightforward to perform and is particularly well-suited for automated nucleic acid extraction platforms. During extraction, nucleic acids are released from the sample under the action of the lysis buffer; nano-magnetic beads then selectively adsorb the nucleic acids in the binding buffer, separating them from other impurities in the sample; The samples are then washed with a washing buffer to remove proteins, polysaccharides, inorganic salts and other contaminants; high-quality RNA is subsequently eluted. This kit does not require the use of toxic reagents such as phenol or chloroform. The extracted RNA yields high yields, high purity and consistent, reliable quality, making it suitable for a wide range of downstream molecular biology experiments.

【Product advantages】

• Highly versatile, suitable for extracting total RNA from a wide range of tissue samples, including animal, plant, fungal and cellular sources.
• Simple to use; the magnetic bead method can be combined with fully automated nucleic acid extraction systems to enable automated extraction, with lysis and binding carried out in a single step for highly efficient extraction.
• No repeated centrifugation is required, ensuring the integrity of the extracted RNA.
• The extraction product is of high purity and yield, with intact electrophoresis bands.
• Safe to use, with no need for liquid nitrogen grinding; the product contains no harmful reagents such as phenol or chloroform.
