| abstractText | The hybridoma PTF-02 secretes an antibody against pig transferrin. Rearranged genes for heavy and light immunoglobulin chains have been studied in the genomes of this hybridoma and in the parent myeloma P3-X63.Ag8.653. The hybridoma was shown to contain three rearranged allelic variants of the heavy chain gene's locus. The gene H2, responsible for synthesis of the heavy chain of the antibody to transferrin, was transmitted in the hybridoma cell from a lymphocyte. Two other genes (H1 and H3) were found both in the hybridoma and parent myeloma genomes. The gene H1 was identified in MOPC21 myeloma, which is a precursor of the X63.Ag8 descendent line. Rearranged k genes were also identified both in the hybridoma and parent myeloma. A functional (K2) gene and a fetal (F) gene appeared in the hybridoma genome from an antigen-stimulated normal lymphocyte. The fetal gene was lost in the course of continuous cultivation of the hybridoma PTF-02 cell line. The gene K1 was transmitted from the myeloma used for fusion. In such a way, the pedigree of rearranged heavy and light chain genes in the hybridoma PTF-02 was established. The results obtained in this work may be relevant to many hybridomas whose immortalizing fusion partner is a MOPC21 derivative, and allow one to identify and isolate functional variable genes to create recombinant constructions. |
