  • Title: The effect of specific antiserum on the metabolism of three membrane-associated antigens of ASL-1 x LM(TK)- hybrid cells.
    Author: Liang W, Cohen EP.
    Journal: Somatic Cell Genet; 1976 Jul; 2(4):291-307. PubMed ID: 1027145.
    Abstract:
    Fusion of ASL-1 cells, a murine leukemia forming thymus leukemia (TL) antigens, with LM(TK)- cells, a TL(--) murine cell line, resulted in a stable hybrid forming TL antigens. The hybrids failed to undergo modulation, the reversible dissappearance of TL antigens from the surfaces of the cells, stimulated by TL antiserum. Unlike ASL-1 cells, the rate of disappearance of the antigens from modulation negative hydrid cells was unaffected by TL antiserum. The t 1/2 of TL antigens of the hybrid was approximately 30 h. The t 1/2 of TL antigens of ASL-1 cells was 10 h in the presence of TL antiserum, 18 h in the absence of TL antiserum. The rate of metabolism of a putative tumor-associated antigen of ASL-1 cells formed by the hybrid was unaffected by exposure to specific antiserum, as was the metabolism of H-2 antigens formed by the cell types.
