● Simple and fast: Ultra-pure total RNA can be obtained quickly.

● Safe and non-toxic: No toxic reagents such as phenol/chloroform.

● High purity: The RNA obtained has high purity and can be directly used for chip detection, high-throughput sequencing and other experiments.

The kit adopts magnetic beads and a unique buffer system, to isolate and purify total RNA with high quality from cell/tissue. The uniquely embedded magnetic beads have a strong affinity for nucleic acid under certain conditions. When the conditions are changed, the magnetic beads can release the absorbed nucleic acid to rapidly separate and purify it.

It can be used to perfectly fit with automated nucleic acid extractor. Through absorption, transfer and release of magnetic beads by the special magnetic bar, magnetic beads and nucleic acid can be transferred to improve the degree of automation. The whole process is safe and convenient, and the extracted RNA has high purity. If high throughput automated extraction is required, TIANGEN can deliver integrated solutions.

RNA purified by this kit is suitable for downstream experiments including RT-PCR, Real Time RT-PCR, chip analysis, Northern Blot, Dot Blot, PolyA screening, in vitro translation, RNase protection analysis and molecular cloning.

Note: GRT431, GDP771H are shipped and stored separately.

Isopropanol (supplementary protocol: samples preserved in Trizol), anhydrous ethanol, homogenization equipment (mortar, homogenizer, etc.), liquid nitrogen, gloves, masks, RNase-Free centrifuge tubes, magnetic racks, or nucleic acid extractor, for other brands of extractor to be integrated, please contact TIANGEN.

Note: Please refer to the recommended ranges in the table below. Do not exceed 100 mg of tissue, otherwise it may lead to RNA yield and quality decrease.

All components of the kit GDP771H can be stored in dry conditions at room temperature (15-30°C) for 15 months. RNase-Free DNase I and RNase-Free ddH₂O can be stored at 2-8°C for 15 months.

● Replace the gloves with new ones frequently. This is because skin often carries bacteria that can lead to RNase contamination.

● Avoid cross-contamination by using RNase-free plastics and tips.

● Pay attention to optimal sample storage and pretreatment conditions to avoid causing degradation of the extracted RNA

Dissolve DNase I dry powder (1500 U) in 1 ml RNase-Free ddH₂O, mix gently and follow the protocol to add 10 μl to each sample for freshly use.

Attention: If long-term storage needed, dissolve DNase I dry powder (1500 U) in 550 μl RNase-Free ddH₂O to make stock solution, mix gently, dispense and store at -30~-15°C (can be stored for 9 months). Add 5 μl stock solution to each sample. Store the DNase I stock solution after thawing from -30~-15°C at 2-8°C (can be stored for 6 weeks) and do not freeze it again.
