Eleven variants producing only heavy (H) chains have been isolated from the P3 cell line after mutagenesis with either ICR 191 or nitrosoguanidine. The H chains produced by these variants are similar both to molecular weight and by peptide maps with the parental H chain. H chains dimerize intracellularly, are not secreted but persist as stable cytoplasmic proteins. No evidence for the continued synthesis of light (L) chains or L chain fragments has been found in these variants. These studies show that, in the P3 cell line, the synthesis of H chains continue in the absence of detectable L chain synthesis.
