How does the bradford assay work
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. A Bradford protein standard curve was produced WebThe Bradford (dye-binding) assay is based on the observation that the absorbance maximum for an acidic solution of the dye Coomassie Brilliant Blue G-250 shifts from 465 nm to 595 nm when binding (adsorption) to basic amino acids occurs.
