Can acetone be used for precipitation of protein from Buffer RLT lysates generated with RNeasy Kits?

Yes, please follow the Supplementary Protocol Acetone precipitation of protein from Buffer RLT or Buffer RLT Plus lysates (RY22).

Important Note:

Do not use TCA to precipitate protein from Buffer RLT and Buffer RLT Plus lysates. These buffers contain guanidine thiocyanate, which can form highly reactive compounds when combined with acidic solutions.

 

For simultaneous purification of DNA, RNA, and protein from the same sample (either cultured cells or easy-to-lyse tissues), we recommend using the AllPrep DNA/RNA/Protein Mini Kit. This kit allows precipitation of protein from Buffer RLT lysates using a novel protein precipitation buffer, Buffer APP.

Please note that Buffer APP is not compatible with Buffer RLT Plus. Acetone should be used instead to precipitate protein from RLT Plus lysates.
