Web1.2 Selecting a Protein Standard In any protein assay, the ideal protein to use as a standard is a purified preparation of the protein being assayed. In the absence of such an absolute reference protein, another protein must be selected as a relative standard. The best relative standard to use is one that gives a color Web布拉德福蛋白質定量法 (Bradford protein assay),亦稱作「考馬斯亮藍法」、「考馬斯藍染色法」(coomassie blue staining),為一種利用 光譜學 技術分析溶液中蛋白質濃度的技術。 本定量法會受待測胺基酸序列影響,此方法為 Marion M.
