Agarose gel electrophoresis of RNA/DNA containing lysates for comparison of enzyme activities of bovine RNase A and RNase PF. N: lysis without addition of RNase, S: lysis with RNase A (Sigma-Aldrich) added to the resuspended cells. RPF: lysis with RNase PF added to the resuspended cells. N + RPF: cleared lysate from lysis N treated with RNase PF. M: DNA molecular size marker
