Soleibao animal tissue nucleic acid, protein stable preservation solution, is a non-toxic and harmless liquid reagent used for collection of animal tissue, only room temperature operation, can quickly stabilize and preserve nucleic acid and protein in tissue. This product is widely used for the stabilization and preservation of RNA, DNA and protein in fresh animal tissue samples or cell samples, such as liver, brain, lung, spleen, kidney, heart, muscle, bone tissue, etc., and can also be used for the preservation of some plant samples. This product will not cause protein denaturation when used for the stability and preservation of the sample protein, and can be followed by Western Blot, SDS-PAGE, enzyme activity determination and other routine protein experiments. After sample extraction, it can be homogenized directly and tissue splitting and protein extraction can be performed by conventional methods. The preservation solution can quickly penetrate into the tissue, completely inhibit RNase, DNase and Proteinase, avoid the degradation of RNA, DNA and Protein, so as to maintain the integrity of RNA, DNA and Protein in the tissue sample. The preservation effect is the same as that of liquid nitrogen when stored in the low-temperature refrigerator at -20℃/-80℃. The RNA, DNA and Protein in the sample can be preserved for a long time.
