Avoid freeze/thaw cycle.ProductsThe Nc-Nucleus/Plasma Protein Extraction Kit is a simple and rapid method for extracting nucleus and plasma proteins from mammalian cells and tissues, and the extracted proteins remain biologically active. The kit first cleaves the cell membrane and releases plasma proteins using the plasma protein extraction reagent, and then centrifuges the nucleus to obtain a nucleus precipitate. Finally, the nuclear proteins are extracted by the nuclear protein extraction reagent. The extracted nuclear and plasma proteins are of high purity, effectively avoiding cross-contamination of nuclear and plasma proteins, and can be used for subsequent operations such as Western, Gel Shift, reporter gene detection and enzyme activity determination.Caveat1. If phosphorylated proteins are to be extracted, add a phosphatase inhibitor to the extraction reagent.2. All sample handling should be done on ice.3. The amount of reagents can be adjusted according to the specific experimental situation to ensure that the ratio of each reagent used is Nc-Buffer A:Nc-Buffer B:Nc-Buffer C = 100:5.5:50.4. Higher speeds can be used for centrifugation.ProcedureI Extraction of cytoplasmic and cytosolic proteins from cells1. Please remove the extraction reagents Nc-Buffer A and Nc-Buffer C for pre-cooling before protein extraction.2. Collect the cells and count them. Centrifuge to remove supernatant.3. 1×107 cells were added with 1 ml of Nc-Buffer A (added to Protease Inhibitor Cocktail at a ratio of 1:99 within 2-3 minutes prior to protein pumping), vortexed for 5 seconds to mix well, and incubated on ice for 20 minutes.Note: The characteristics of various cells are different, and the amount of Nc-Buffer A needs to be adjusted according to the characteristics of different cells. If the protein concentration is small, reduce the amount of Nc-Buffer A and subsequent Nc-Buffer B and Nc-Buffer C proportionally.4. Add 55 µl of Nc-Buffer B, vortex for 5 seconds to mix thoroughly, and incubate on ice for 1 minute.5. Centrifuge at 12,000 rpm (~13,400 x g) for 15 minutes at 4°C, collect the supernatant (as clean as possible) into a new centrifuge tube and store at -20°C (this extract is cytoplasmic protein).6.

Add 200 to every 1 mL of TRIzon Reagent µ LTRIzon PaI ™， Cover the tube tightly, vigorously shake for 15 seconds, and let it sit at room temperature for 2 minutes.4. Centrifuge at 4 ℃ 12000 rpm (~13400 × g) for 10 minutes. At this time, the sample is divided into three layers: the red organic phase, the middle layer, and the upper colorless aqueous phase. RNA is mainly in the upper aqueous phase. Move the upper aqueous phase to a new RNase Free centrifuge tube (provided).5. Add an equal volume of 70% ethanol (prepared without RNase water) to the obtained aqueous solution, invert and mix well.6. Add all the solutions obtained in the previous step to the spin columns RM that have been loaded into the collection tube. If the solution cannot be added at once, it can be transferred in multiple batches. Centrifuge at 12000 rpm for 20 seconds, discard the waste liquid in the collection tube, and place the adsorption column back into the collection tube.7. Add 350 to the adsorption column µ L Buffer RW1, centrifuge at 12000 rpm for 20 seconds, discard the waste liquid in the collection tube, and place the adsorption column back into the collection tube.8.
