[The use of monoclonal antibodies for purification of ribonuclease H from E. coli].

Monoclonal antibodies to E. coli ribonuclease H were obtained from two hybrid clones. Using the monoclonal antibodies two immunosorbents were synthesized for RNase H which have a slight difference in the capacity and do not differ in the conditions of antigen elution. A homogeneous (according to electrophoresis in PAAG) preparation of the enzyme was obtained using the synthesized immunosorbents.
