About Bradford complex (595 nm) Concentration from Absorbance
Use the Beer–Lambert law to convert an absorbance reading of Bradford complex (595 nm) into molar concentration, using its extinction coefficient (43,000 M⁻¹cm⁻¹). The calculation uses c = A / (ε · l). Why it matters: The Beer–Lambert law is only linear in a window (≈0.1–1.0 absorbance). Quantitation outside it, or with the wrong extinction coefficient, silently biases every concentration you report. Bradford complex (595 nm): ε = 43,000 M⁻¹cm⁻¹ at the stated wavelength. Before you trust the number, double-check: reading absorbance above ~1.0 without diluting; using a molar ε with a mass concentration; wrong path length (not 1 cm). Everything is computed on your own device — nothing you enter is uploaded — so the tool is safe for unpublished sequences, proprietary formulations and sensitive measurements, and easy to cite in a methods section or lab SOP.
