Low protein concentration
WebOur SDS-PAGE Clean-Up Kit is designed for the preparation of samples that are difficult to analyze due to the presence of salts or a low protein concentration. Step 2. Gel Electrophoresis: Electrophoresis is the second step,step and is a commonly used method for separating proteins based on size, shape, and/or charge. WebThe kit has been optimized for determining total protein content in low protein concentration samples (0.5-40 μg/mL), even in the presence of detergents. The assay is based on the reaction of bicinchoninic acid (BCA) with the cuprous cation (Cu 1+ ), which is generated by reduction of cupric cation (Cu 2+) by the protein in alkaline conditions.
