title: Quantitative approaches for studying gene expression.
abstract: The methods currently available for measuring mRNAs and proteins are reviewed, with a special emphasis on their application to physiological questions. The article focuses on the quantitative determination of cellular contents, but also on assessment of rates of synthesis and degradation, and turnover.
