WebThe Quick Start Bradford protein assay is a quick, simple, and inexpensive laboratory procedure to determine the protein content of a sample. The assay is based on the color development formed when the dye, Coomassie Blue G-250, binds to protein. The simplicity of the assay allows the results to be read directly in cuvettes or test Webbiuret test, Bradford test, (2)bicinchoninic acid assay (BCA assay) and Lowry test. No one reagent can be considered to be the ideal or best protein assay method. Each method has its advantages and disadvantages (Table 1). The choice among available protein assays is usually based on the compatibility of the protein assay method with the samples.
