RNAfixer: RNA Stabilization Reagent

Description RNAfixer is a aqueous and nontoxic tissue-holding liquid, which can in situ stabilize and protect RNA under non-frozen situation by rapid infiltrating fresh tissues and not affect RNA yield and integrality. Hence, RNAfixer eliminates inconveniences to flash freeze samples in liquid nitrogen or take samples from different places. When fresh tissues immerged into RNAfixer, RNA can be stored up to a day at 37°C, a week at 25 °C, a month at 4°C and a long term at -20°C or -80°C. RNA virus (such as HCV and HIV) is stable up to a month at 37°C in RNAfixer. Features Ready-to-use: just sheer the tissues into appropriate volume and put into RNAfixer, then no RNA degradation. No liquid nitrogen needed: Because samples storage dose not need liquid nitrogen, dry ice or -80°C refrigerator, RNAfixer is convenient for fast and large-scale samples collection. Transportation facility: Because samples are stable up to one week at 25°C, samples can be mailed or transported in usual way, which is benefit for academic communication. RNA stability: multiple freeze-thaws and diversified treatments do not affect RNA stability for samples stored in RNAfixer. Data repetibility: RNAfixer can reduce the error produced in large-scale samples treatments and increase reliability of data produced in different tests, which is especially useful to large-scale gene expression profile. Full compatibility: Samples in RNAfixer can not only be used for all total RNA extraction kits, but also can be employed for tissue slice, immunoassay and flow cytometry with no effect on extracting RNA.
