    This study introduces a rapid electrofusion method for creating somatic cell hybrids. This technique significantly increases hybrid clone generation efficiency compared to traditional methods.

    Area of Science:

    • Cell Biology
    • Genetics
    • Biotechnology

    Background:

    • Somatic cell hybridization is crucial for genetic research and biotechnology.
    • Existing methods like polyethylene glycol (PEG) fusion have limitations in efficiency and speed.

    Purpose of the Study:

    • To develop a rapid and highly efficient method for generating viable somatic cell hybrids.
    • To compare the efficiency of electrofusion with PEG-induced fusion.

    Main Methods:

    • Co-culture of ID and CH rodent cell lines.
    • Exposure to five successive electric pulses (1.5 kV/cm, 50 μsec).
    • Selection, propagation, karyotyping, and enzyme marker analysis of hybrid clones.

    Main Results:

    • Extensive cell fusion and hybrid clone generation.

  • Hybrid clone frequency of 1 x 10^-3, a 100-fold increase over PEG fusion.
  • Successful propagation and characterization of 17 hybrid clones.

    • Conclusions:

    • Electrofusion is a highly efficient and rapid method for somatic cell hybridization.
    • This technique offers a significant improvement over conventional PEG-induced fusion.
    • The generated hybrid clones are viable and can be characterized for their hybrid nature.
