title: [About the heterogeneity of the murine oncornavirus group-specific antigen gs-1 (author's transl)].
abstract: In isoelectric focusing of twofold gradienpturified and Tween 80-ether disrupted RLV the groupspecific antigen (gs-1) was found in 3 pH-zones (4,45-5,5; 5,65-6,0; 6,45-6,6). For the gs-1 from plasma und spleen cells of leukemic mice was shown heterogeneity by several methods: 1. Gs-1 from plasma showed in isoelectric focusing a scattering along the whole elution profile. 2. Agarimmunoelectrophoresis resulted in a longer precipitationline for gs-1 from plasma in comparison with gs-1 from spleen cells. 3. Polyacrylamidgelelectrophoresis with following immunodiffusion made evident the particularly discrete character of this heterogeneity: gs-1 from both materials were found in two main zones.
