Bio-Rad, 5000121, RC DC ™ Protein Assay Kit I

Colorimetric assay kit, includes RC Reagents Package, DC ™ Protein Assay Reagents Package, bovine γ-globulin standard; 450 standard assays
Overview
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
