Any idea of the composition of the RNA Wash Buffer from Zymo Research RNA Clean - (Mar/17/2014 )

Dear all,

 

does anybody has any idea concerning the composition of the RNA Wash Buffer from Zymo Research RNA Clean & Concentrator kit? It contains EtOH (80%), so I guess whether I can simply use 80% EtOH as "backup" when the buffer is almost finished.

 

Thanks,

 

all the best,

 

Mark

A guess -- it would be buffered at pH 7.5 (or perhaps lower -- you could measure it) likely with Tris. Make sure it is RNAse free.
