The Bradford Method For Protein Quantitation

A rapid and accurate method for the estimation of protein concentration is essential in various areas of biology and biochemistry. An assay originally described by Bradford (1) has become the preferred method for quantifying protein in many laboratories. This technique is simpler, faster, and more sensitive than the Lowry method. Moreover, when compared with the Lowry method, it is subject to less interference by common reagents and non-protein components of biological samples (see Note 1). Despite the introduction of alternative protein assays, the Bradford method remains a popular technique, with the original article (1) being cited over 3,500 times in primary research papers in 2006, thirty years after its…
