Protein Purification Table Calculations: Formulas, No Numbers

This video tutorial covers the steps to create a purification table, focusing on enzyme purification and activity assays. It explains the Bradford assay for determining protein concentration and details the calculations for enzyme concentration, activity per milliliter, specific activity, and total enzyme units. The video aims to clarify common misunderstandings in biochemistry labs and sets the stage for further discussions on percent yield and fold purity in subsequent videos.
