Understanding the Bradford Assay

What is the primary purpose of the Bradford assay?

• To measure the acidity of a solution

• To quantify protein concentration

• To identify the presence of carbohydrates

• To determine the molecular weight of proteins

How does Coomassie Brilliant Blue G250 interact with proteins?

• It interacts with basic amino acids like lysine

• It reacts with the carbohydrate chains of proteins

• It binds to the lipid components of proteins

• It forms hydrogen bonds with water molecules

What is required to calculate the protein concentration of an unknown sample using the Bradford assay?

• A reference solution with known protein concentration

• A solution with a pH of 7

• A high concentration of Coomassie dye

• A temperature-controlled environment

Which of the following is an advantage of the Bradford assay?

• It is unaffected by detergents

• It requires a high temperature to perform

• It is highly sensitive and quick

• It can only be used with non-acidic solutions

What is a limitation of the Bradford assay?

• It cannot detect proteins at low concentrations

• It is dependent on the protein's amino acid composition

• It is not suitable for use at room temperature

• It requires complex equipment
