Lambda-Chain Production in Human Lymphoblast-Mouse Fibroblast Hybrids

RESUMO
Mutant human lymphoblast cells deficient in hypoxanthine phosphoribosyltransferase (EC 2.4.2.8) activity were hybridized with thymidine kinase (EC 2.7.1.21)-deficient mouse fibroblasts. Hybrid cells were readily selected, as both parental lines were nonreverting and eliminated by hypoxanthine-amethopterinthymidine medium. Human lambda (λ) chain was the only immunoglobulin chain produced by the lymphoblast parent, as determined by immunofluorescent techniques. Two independent hybrid clones chosen for detailed study synthesized human λ chain, and continued to do so after prolonged culture.
