title: A polyethylene glycol-based radioimmunoassay for gastrin.
abstract: Precipitation with polyethylene glycol 6000 is a satisfactory technique for "bound from free" separation in gastrin radioimmunoassay (RIA). This reagent, however, cannot be used in stoichiometric invertase-peptide conjugate-based enzyme immunoassays.
