Expression of spleen cell immunoglobulin phenotype in hybrids with myeloma cell lines. 1981

M R Clark, and C Milstein

Fusions were performed between myeloma cell lines, of mouse and rat origin, and mouse or rat spleen cells. Two statistical methods have been used to measure the proportion of hybrids expressing a spleen cell-derived immunoglobulin phenotype, one of them applicable to cells growing under nonlimiting dilution conditions. The results indicate that there is strong preferential selection for hybrid cell growth with an immunoglobulin-secreting phenotype. The degree of preferential selection is dependent upon the myeloma cell line used and is most marked in the case of the rat myeloma lines. Surviving hybrids seem to originate from fusions of myeloma and spleen B(but not T) cells, but immunoglobulin production is lost more readily in certain combinations.

UI	MeSH Term	Description	Entries
D007136	Immunoglobulins	Multi-subunit proteins which function in IMMUNITY. They are produced by B LYMPHOCYTES from the IMMUNOGLOBULIN GENES. They are comprised of two heavy (IMMUNOGLOBULIN HEAVY CHAINS) and two light chains (IMMUNOGLOBULIN LIGHT CHAINS) with additional ancillary polypeptide chains depending on their isoforms. The variety of isoforms include monomeric or polymeric forms, and transmembrane forms (B-CELL ANTIGEN RECEPTORS) or secreted forms (ANTIBODIES). They are divided by the amino acid sequence of their heavy chains into five classes (IMMUNOGLOBULIN A; IMMUNOGLOBULIN D; IMMUNOGLOBULIN E; IMMUNOGLOBULIN G; IMMUNOGLOBULIN M) and various subclasses.
