Abstract

Immunoglobulin synthesis by 16 long-term suspension cultures of mononuclear cells derived from peripheral blood of nine patients with heterophile-positive infectious mononucleosis (IM) has been demonstrated by radioimmunoelectrophoretic techniques. All cell lines synthesized molecules with IgG (γ) heavy chain specificity. 14 cell lines produced molecules with IgM (μ) heavy chain specificity and 11 cell lines produced molecules with IgA (α) heavy chain specificity. No detectable synthesis of molecules with IgD (δ) heavy chain specificity was observed by these cell lines derived from peripheral blood of patients with IM. 13 cell lines produced molecules with type K (κ) light chain specificity and 6 cell lines produced molecules with type L (λ) light chain specificity. Of interest, 9 of 16 lines produced IgG (γ), IgA (α), and IgM (μ) heavy chain molecules and 5 of these cell lines produced molecules with type K (κ) and type L (λ) light chain specificity as well.
