Bradford coefficient

In summary, in order to find a standard curve, one must use varying concentrations of BSA (Bovine Serum Albumin) in order to create a standard curve with concentration plotted on the x-axis and absorbance plotted on the y-axis. Only a narrow concentration of BSA is used (2-10 ug/mL) in order to create an accurate standard curve. Using a broad range of protein concentration will … WebThere are several methods for determining the concentration of protein in samples and reagents. Among them, the BCA, Bradford, and ultraviolet (UV) methods are the most …
