title: [Modified method for producing ribonuclease A from amorphous and crystalline ribonucleases].
abstract: The paper describes a method for producing gram-scale quantities of beef pancreatic ribonuclease A (RNase A) (EC 3.1.4.22) from commercial, amorphous and crystalline RNases. The method involves enzyme purification by chromatography on SP-Sephadex G-25, rechromatography on Bio-Rax 70 followed by concentration, storage and desalting in optimal conditions. In their properties the resultant preparations of RNase A are not inferior to the best commercial samples of the enzyme.
