A typical animal cell is thought to contain some 10 billion protein molecules that need to be sorted into their proper compartments. That’s a lot of proteins! Can 10 billion proteins even fit into a cell? The average length of a human protein is 450 amino acids, and the average mass of an amino acid in a protein is 110 daltons (1 dalton = 1 g/mol). Given that the average density of a protein is 1.4 g/cm3, what fraction of the volume of a cell would 10 billion average protein molecules occupy? Consider first a liver cell, which has a volume of about 5000 µm3. Then consider a pancreatic β cell, which has a volume of 1000 µm3.

You are given a protein solution with a concentration of 0.15 mg/ml. Suppose that we want to prepare a solution containing 100 μg of the protein at a concentration of 1 mg/ml. To achieve this, we will first dry down enough protein solution to obtain 100 μg of proteins. How much solution do we need for drying down? How much volume of H2O do we need to add to the dried protein to obtain the desired concentration?
