potassium tartrate/leukemia

The Rauscher leukemia virus separated as a single band upon density gradient centrifugation in cesium chloride, rubidium chloride, sucrose, potassium citrate, or potassium tartrate. Prolonged exposure to concentrated potassium citrate or potassium tartrate solutions caused lysis of the virus; the

The B-IV and B-IX zonal ultracentrifuge rotors were applied to the concentration and purification of the Moloney and Rauscher murine leukemia viruses from large volumes of infected tissue culture fluids and animal materials. Potassium tartrate, potassium citrate and sucrose gradients were used to

Arsenic trioxide (As2O3) has been used with success in the treatment of acute promyelocytic leukemia. However, resistance to arsenite agents reduces their efficacy. We have isolated arsenite-resistant human epidermoid carcinoma KB cells, termed KAS. KAS cells were resistant to sodium arsenite

A virus resembling type C murine leukemia viruses, which is associated with transplantable hamster tumors, was partially characterized with respect to certain biological, biophysical, and cytochemical features. As determined by electron microscopy, high concentrations of the virus appeared in the

Immune serum was prepared in the rabbit with BAI strain A leukosis virus isolated by centrifugal fractionation from the plasma of chickens with myeloblastic leukemia and further purified on a potassium tartrate gradient. Antibody to group-specific antigen was demonstrated in the serum by

Arsenic trioxide (ATO) is used as a chemotherapeutic agent for the treatment of acute promyelocytic leukemia. However, increasing drug resistance is reducing its efficacy. Therefore, a better understanding of ATO resistance mechanism is required. In this study, we established an ATO-resistant human
