A new equipment detergent has been developed based on the deoiling synergism of ethylene glycol monobutyl ether, surfactant and alkaline assistant, and combined with the deoiling characteristics of organic solvent and water-based detergent.

Thus it is presented an effective RNA extraction method based on the nuclease adsorbent macaloid,poly vinyl pyrrolidone,and high concentration of KAc and ethylene glycol monobutyl ether,which has successfully extracted high-quality RNA from many materials difficult to RNA isolation,such as RNase-rich rabbit liver,plant and microbial tissues rich in polysaccharides,lipids and polyphenol compounds.
