โฆ Synopsis
The variation in the sensitivity of proteins to some commonly used protein assay procedures was estimated by a calculation of the ideal titer per unit weight of protein for a sample of 350 proteins. On the basis of such calculations, the variation expected of nitrogenbased assay procedures is expected to be small, and such procedures are considered to give a more consistent quantification of a variety of proteins than other commonly used assay procedure.

A solid-phase protein assay (SPA) for the determination of protein concentrations in the nanogram range is described. The technique is based on biotinylation of immobilized protein on the solid phase of a microtiter plate and quantitation of the protein-biotin complexes by peroxidase-coupled avidin.
