Choose AnswerChoose the Best Answer

A

Calibration curves are created using known protein concentrations to interpolate the concentration of unknown samples based on absorbance values from the Bradford assay.

B

The Bradford assay directly measures the weight of the protein before calibration curves are applied.

C

Sample preparation for the Bradford assay does not require calibration curves as protein concentrations are always known.

D

Calibration curves are only relevant for spectrophotometric methods other than the Bradford assay.

Understanding the Answer

Let's break down why this is correct

The Bradford assay creates a calibration curve using proteins of known amounts. Other options are incorrect because Some think the assay weighs protein directly; It is not true that calibration curves are unnecessary.
