Abstract excerpt
We have examined the stability of trinitrophenyl (TNP) -specific IgM production in hybridoma cell lines in which homologous recombination was used to change the variable region of an endogenous chromosomal immunoglobulin kappa gene to one specific for TNP. Mutant hybridomas that have lost TNP-specific IgM production are detected with a frequency of approximately 1%. Characterization of the mutant cells reveals a...
