Protein Purification & Isolation

Proteins play an integral role in cell structure and function. In biochemistry, a protein is a polymer of amino acids arranged in the form of polypeptide chains. In order to study proteins, it’s important to first identify and isolate them. To accomplish this, biochemists carry out high-throughput protein purification.
