500-0122-MSDS DC Universal Protein Assay Kit II English

Use the RC DC Protein Assay for samples containing reducing agents and detergents. This assay, based on the DC Protein Assay, is a modified form of the Lowry assay that is both reducing agent compatible (RC) and detergent compatible (DC), whereas the DC Assay is only detergent compatible.

  • Linear over a wide range of protein concentration; standard assay, 0.125–1.5 mg/ml and low concentration assay, 5–250 µg/ml
  • Read wavelengths, 650–750 nm
  • Absorbance values are stable ≥ 1 h
  • Quantitate protein in sample loading buffer prior to gel electrophoresis, either 1-D or 2-D format
  • Determine protein recovery in cell lysates
