Questions & Step-by-Step Solutions

Which method can be used to determine the purity of a protein sample?
  • Step 1: Understand that protein purity means how much of the sample is the desired protein compared to other substances.
  • Step 2: Learn about mass spectrometry, which is a technique that measures the mass of proteins to identify and quantify them.
  • Step 3: Recognize that Western blotting is another method that uses antibodies to detect specific proteins in a sample.
  • Step 4: Realize that both methods can help you see if your protein sample is mostly the protein of interest or if it has impurities.
