Question & Answer
Choose the Best Answer
The use of incorrect dilutions of the standard samples
The standard curve was plotted using incorrect units
The reagents used in the assay were outdated
The laboratory temperature was constant throughout the experiment
Understanding the Answer
Let's break down why this is correct
When the standard samples are not diluted correctly, the concentrations used to build the curve are wrong. Other options are incorrect because Using the wrong units for the curve does not change the shape of the data if the same mistake is made everywhere; Old reagents may make the assay less sensitive, but they do not systematically shift all absorbance readings.

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.
