Techniques for Decreasing the Toxicity of Polyethylene Glycol

  • W. Edward Mercer

Abstract

In recent years the use of the chemical fusogen polyethylene glycol (PEG) in place of inactivated Sendai virus (Harris and Watkins, 1965) has greatly facilitated somatic cell fusion experiments (Pontecorvo, 1975; Davidson and Gerald, 1976a). There are, however, some inherent problems associated with PEG-induced cell fusion. One problem is that PEG will effectively induce cell-to-cell fusion only within a very narrow range of concentrations (Davidson et al., 1976b), and as the optimum concentration of 50–55% is approached the cytotoxic effects from exposure to the fusogen become significant.
