WebOne of the major advantages of the BCA assay is that it produces a linear response curve. This response curve allows accurate determination of unknown protein concentrations and provides a higher dynamic range than other standard assays. Figure 3. Standard curves for protein quantitation assays. WebA standard curve is obtained by plotting absorbance versus amount of substance X. If the relationship is clearly linear, a standard curve isn't even necessary. Amounts can be determined using interpolation. A curve should be constructed the first time an assay is used, to check for accuracy and linearity. Example of a standard curve
