Profile: Dongsheng Biotech Co., Ltd. focuses on R & D and production base of molecular biology reagents. We deal with PCR products, DNA purification, DNA electrophoresis products, cloning and general RNA extraction kit. The general eco-friendly RNA extraction kit provides a simple, reliable, and rapid method for isolating total RNA from a wide variety of samples, including animal and plant cells and tissue, bacteria, and yeast. Total RNA isolated by eco-friendly RNA extraction kit is free of protein and DNA contamination. It can be used for Northern blot analysis, dot blot hybridization, poly (A)+ selection, in vitro translation, RNase protection assay, and molecular cloning. RNA stablilization solution is an aqueous tissue storage reagent that stabilizes and protects cellular RNA in intact, unfrozen tissue samples. RNA stablilization solution eliminates the need to immediately process tissue samples, or to freeze samples in liquid nitrogen for later processing. Tissue pieces can be harvested and submerged in RNA stablilization solution for storage, without jeopardizing the quality or quantity of RNA obtained after subsequent RNA isolation. RNA stablilization solution can be added to cell pellets and even cells in medium. The samples can then be stored, frozen or unfrozen.
