title: The colorimetric detection and quantitation of total protein.
abstract: Protein quantification is an important step for handling protein samples for isolation and characterization; it is a prerequisite step before submitting proteins for chromatographic, electrophoretic, or immunochemical analysis and separation. Colorimetric methods are fast, simple, and not laborious. This unit describes a number of assays able to detect protein concentrations in the low microgram to milligram per milliliter ranges in a variety of formats.
