abstract：:The N-glycans have been removed by peptide-N-glycosidase F (PNGase F) from purified human non-secretory RNases derived from kidney, liver and spleen. The spleen RNase was purified by two procedures, one of which did not include the usual acid treatment step (0.25 M H2SO4, 45 min, 4 degrees C), to determine if acid tre...
