FAQ: Can I use RNase Inhibitor, Murine (Glycerol-free) in PURExpress® In vitro Protein Synthesis and NEBExpress Cell-free E. coli Protein Synthesis workflows? 

Yes, with one exception. We do not recommend using RNase Inhibitor, Murine (Glycerol-free) with the PURExpress Δ (aa, tRNA) Kit (NEB #E6840S) due to slight variations in the enzyme’s formulation that may interfere with this kit.
