Question & Answer
Choose the Best Answer
The absorbance readings of all samples should be taken at different wavelengths.
The standard curve must be generated using the same diluent and assay conditions as the unknown samples.
The standard curve should include a broad range of protein concentrations beyond that of the unknown sample.
The standard curve only needs to be generated once, regardless of changes in reagent batches.
Understanding the Answer
Let's break down why this is correct
Using the same diluent and assay conditions for both the standards and the unknown keeps the chemistry the same. Other options are incorrect because Reading absorbance at many wavelengths mixes up the signal; A very wide concentration range is not needed if the unknown is inside the curve.

Definition
Standard curve generation is a fundamental aspect of protein measurement methods, used to correlate protein concentrations with colorimetric readings. By plotting known protein concentrations against corresponding absorbance values, a standard curve is created to quantify unknown protein samples accurately.
