What is the column cut-off size for the RiboPure RNA Purification Kits?
The column cut-off size is 200 nt. Using a RiboPure kit is not appropriate for miRNA recovery. For miRNA isolation, we would suggest using a mirVana kit, the TRIzol Plus RNA Purification Kit, or the PureLink RNA Micro Kit.
What are the differences in technology between the PureLink RNA Mini Kit and RiboPure RNA Purification Kits?
The PureLink RNA Mini Kit provides rapid column-based purification of total RNA, without organic lysis (phenol/chloroform). You can obtain up to 1,000 µg of purified RNA from a single extraction. The RiboPure RNA Purification Kits combine a phenol/guanidine thiocyanate solution with a glass-fiber filter purification method.
