Products Introduction

This kit is suitable for simple, rapid and efficient isolation and purification of DNA/RNA from whole blood, tissue homogenates, swabs, serum, plasma and other cell-free body fluids, etc. The unique buffer system enables the viral nucleic acids in the lysate to bind to the silica gel centrifugal adsorbent columns in a highly efficient manner, and the viral nucleic acids obtained are of high purity and stable quality, free of protein, nuclease and other impurities, and can be used in a variety of routine operations, including PCR, fluorescence quantitative PCR and other experiments. It can be used for a variety of routine operations, including PCR, fluorescence quantitative PCR and other experiments.

Pre-experiment Preparation and Important Notes

1. Read these instructions carefully before experimenting.

2. If Proteinase K is to be stored for a long period of time, please keep it at -20℃.

3. Check Buffer RLC for crystallization or precipitation prior to use, and if crystallization or precipitation occurs, redissolve Buffer RLC in a 56°C water bath.

4. Pre-treatment of tissue samples: Take 20 mg of tissue samples into 1.5 mL centrifuge tubes (self-provided), add 500 μL of Buffer RLC, and after the tissue homogenizer breaks up, centrifuge the samples for 1 minute at 12,000 rpm (~13,400×g), and take 200 μL of supernatant as samples.

procedure

1. Take a 1.5 mL centrifuge tube (provided), add 500 μL of Buffer RLC, 200 μL of sample, 20 μL of Proteinase K, vortex for 5 s, and then place it in a thermostatic mixer at 1200 rpm for 10 min at room temperature. Note: For wet swab samples, 200 μL of sample was taken after sufficiently shaking and mixing. Note: For wet swabs, 200 μL was taken from the sample after it was soaked in 400 μL of saline, shaken and mixed thoroughly for 5 minutes, and then centrifuged at 12,000 rpm for 1 minute, and 200 μL was taken for extraction.

2. Instantly remove the centrifuge tube and add the solution from step 1 to the Spin Columns DM in the collection tube. centrifuge at 12,000 rpm (~13,400 x g) for 1 minute, pour off the waste liquid from the collection tube, and return the column to the collection tube.

3. Add 500 μL of Buffer PGWT to the adsorbent column, centrifuge at 12,000 rpm for 1 minute, pour off the waste liquid from the collection tube, and return the column to the collection tube.

4. Add 500 μL of Buffer GWT2 to the adsorbent column, centrifuge at 12,000 rpm for 1 minute, pour off the waste liquid from the collection tube, and return the column to the collection tube.

5. Centrifuge at 12,000 rpm for 2 minutes and pour off the waste liquid in the collection tube. Place the adsorption column at room temperature for 2 minutes and allow to dry.

6. Place the column in a new collection tube (RNase-Free Centrifuge Tube), add 40-100 μL of RNase-Free Water to the center of the column membrane, let it stand at room temperature for 2 minutes, and then centrifuge at 12,000 rpm for 1 minute to collect the nucleic acid solution. Store at -80℃ for a long time.
