WebDec 18, 2024 · How does Bradford solution work? How the Bradford Protein Assay Works. The Bradford protein assay is a time-tested colorimetric assay. When the Bradford reagent (acidified Coomassie Brilliant Blue G-250) binds to proteins, the dye undergoes a color change in the visible spectrum, with the absorbance maximum moving from 470 to 595 nm. WebThe Bradford assay in the 96‑well microplate format has a calculated limit of detection of ~138 µg/mL for BSA. The assay can also be performed in a low range format further extending the dynamic range to submicrogram per mL concentration determinations (data not shown). Figure 3. Bradford assay.
