Involvement of host DNA gyrase in growth of bacteriophage T5
(1986)
Bacteriophage T5 did not grow at the nonpermissive temperature of 42°C in Escherichia coli carrying a temperature-sensitive mutation in gyrB [gyrB(Ts)], but it did grow in gyrA(Ts) mutants at 42°C. These findings indicate ...
Monoclonal antibodies to bull sperm surface antigens
(1985)
Four monoclonal antibodies were generated during the present investigation. Mice were immunized with washed ejaculated bull spermatozoa. Spleen cells from the immunized mice were fused with myeloma cells (SP2/0) and four ...
Separation of the complexes formed between the regulatory and catalytic subunits of cyclic adenosine monophosphate-dependent protein kinase and topoisomerase I activity in preovulatory follicle-enriched immature rat ovaries
(1989)
Our previous studies have shown that the regulatory subunits of the type II form of cAMP-dependent protein kinase (R‖) present in soluble extracts of immature rat ovaries elute from diethylaminoethyl-cellulose as three ...
