title: A new dimension in suspension fusion techniques with polyethylene glycol.
abstract: Polyethylene glycol (PEG) induces the hybridization of mammalian cells at a much higher frequency when the cells are attached to a substrate during treatment than when the cells are treated in suspension. Since many cell types, e.g., lymphocytes, cannot attach to a substrate, a new technique for the PEG-induced fusion of cells in suspension was developed. This technique, referred to as "pancake fusion," is based on the centrifugation of suspended cells onto a coverslip and the PEG treatment of the cells on the coverslip as if they were attached to a substrate. With this technique, the frequency of hybridization of human white blood cells, which are incapable of attaching to a substrate, can be greatly increased.
