R J Klebe, M G Mancuso

    Somatic Cell Genetics
    |July 1, 1981
    PubMed
    Summary

    Researchers screened 118 agents to find new cell hybridization compounds like poly(ethylene glycol) (PEG). Over 20 effective agents were identified, including modified PEG derivatives, offering alternatives for cell fusion applications.

    Area of Science:

    • Biotechnology
    • Cell Biology
    • Polymer Chemistry

    Background:

    • Poly(ethylene glycol) (PEG) is the standard agent for inducing cell hybridization.
    • Identifying alternative compounds with similar efficiency is crucial for broader applications.

    Purpose of the Study:

    • To screen membrane-active agents for cell hybridization properties comparable to PEG.
    • To identify novel compounds and PEG derivatives that can efficiently induce cell fusion.

    Main Methods:

    • A screening procedure using the standard method for PEG-induced cell hybridization was employed.
    • 118 different membrane-active agents were tested for their ability to promote cell fusion.

    Main Results:

    • Over 20 compounds were identified as effective cell hybridization agents, showing efficiency similar to PEG.
    • Branched, charged, and chemically altered PEG derivatives retained activity, while hydrophobic derivatives were generally inactive.
    • Several commercially important PEG derivatives showed high efficiency in cell hybridization.

    Conclusions:

    • Novel compounds and modified poly(ethylene glycol) derivatives can efficiently induce cell hybridization.
    • The study identified potential alternatives to PEG for cell fusion, with implications for pharmaceutical and cosmetic industries.
    • The biohazard of these compounds was considered, and a simplified method for PEG preparation and use was presented.
