RNase remover spray

Cat. No. RNase remover spray
183123
Molecular biology
Application:
RNase Remover Spray is a cleaning agent for the removal of RNase contamination from glass and
plastic surfaces. It is effective for cleaning work areas, pipettors and equipment that must be
RNase-free, e.g. at eliminating RNase contamination from microcentrifuge tubes without interfering
in subsequent enzymic reactions.

Appearance of solution Clear foamy liquid RNase activity Not detected
Performance of spray Passes test Protease activity Not detected
Composition Complies
