title: Analysis of thy-1 variants of murine lymphoma cells.
abstract: Cells obtained from a radiation-induced T-cell lymphoma of BALB/c mice, RLmale-1, were adapted to long-term tissue culture. Clones of cells were obtained in soft agar and a clonally derived population studied for the frequency of mutation in the expression of the surface antigen Thy-1.2 (OC3H) by immunoselection. The mutation rate was 1.05-1.50 X 10(-6) per cell per generation. Antigenic and structural analysis of prototype positive and negative clones demonstrated clear differences between them.
