A
It provides a direct comparison between absorbance and an unknown concentration.
B
It eliminates the need for any colorimetric reagents.
C
It only works for a specific protein type and cannot be generalized.
D
It measures absorbance without any calibration against known standards.
Understanding the Answer
Let's break down why this is correct
Answer
By measuring the absorbance of a set of known protein concentrations, you create a standard curve that links absorbance to amount of protein. When you test an unknown sample, you read its absorbance and locate that point on the curve to find the corresponding concentration. This works because the curve captures the linear relationship between absorbance and protein amount, correcting for variations in reagents or instrument sensitivity. For example, if the curve shows that 0. 5 absorbance units equal 10 µg/mL, an unknown sample with 0.
Detailed Explanation
A standard curve lets you match the light a sample absorbs to a known protein amount. Other options are incorrect because The idea that color reagents are unnecessary is a misconception; The belief that a curve works only for one protein type is wrong.
