Key Terms

Spectrophotometry
A method to measure how much light a sample absorbs.

Example: Using a spectrophotometer to measure protein concentration.

Bradford Assay
A colorimetric protein assay based on the binding of Coomassie Brilliant Blue dye to proteins.

Example: Using the Bradford assay to quantify protein in a cell lysate.

BCA Assay
A colorimetric assay that uses bicinchoninic acid to detect proteins.
