title: Multicomponent radioimmunoassay: simultaneous measurement of choriomammotropin and pregnancy-specific beta1-glycoprotein in pregnancy serum.
abstract: We describe a receptacle for use in the simultaneous radioimmunoassay of two serum constituents in a single sample, and the application of this principle for the measurement of human pregnancy serum choriomammotropin and pregnancy-specific beta 1-glycoprotein. The analytical performance of this multicomponent radioimmunoassay approaches that of conventional radioimmunoassays. By following the principle described, it is likely that large numbers of constituents can be efficiently measured in single samples.
