Proposals for Standardization of Total Protein Assays

Abstract

Abstract The Standards Committee of the AACC presents a discussion of the nature of total serum protein and the problems associated with its determination. Proposals are made that protein be defined as polypeptide material, and that a reference preparation be promulgated for interlaboratory use. The reference material suggested is bovine serum albumin, produced to rigid specifications and distributed as a stable 7% (w/v) solution, the concentration of which has been established by careful dry weight assay. Comments of readers are invited.
