Abstract:

Taking the rabbit blood as the material, which are extracting total RNA by the traditional method of TRLzol and the RNA Extraction Kit. It had measured 260n 320 nm, 230 nm and 280 nm of sample luminosity By uv spectrophotometry , and estimate the purity and concentration of RNA .The results indicated that compared to the method of TRIzol，the RNA Extraction Kit was more High quality ,simple and fast.
