title: [Isolation of low-molecular weight fractions from the splenic tissue of calves that inhibit the proliferation of leukemic cells in mice].
abstract: The three-stage scheme of extracting the low-molecular weight biologically active substances from spleen tissue has been suggested. It includes the following steps: adsorption chromatography on hydroxyapatite, ion-exchange chromatography on DEAE-matrices and gel-filtration. The resulting pool of low-molecular substances inhibits the 3H-thymidine incorporation into DNA of cultured leukemic cells.
