3. You are given a mixture of four proteins, whose properties are listed in the table below. Propose a process to purify each protein so that you end up with four solutions of pure protein. What resin would you use to bind the protein(s)? What changes to the buffer would you make to desorb the protein(s)? Contains an N-terminal His6-tag. Two 50 kDa subunits contain a non-heme Fe2+ in the active site. Protein Size (kDa) pl Specific Properties A 100 6.0 B 40 7.7 C 240 8.3 Ꭰ 225 5.5 Contains FAD redox center and an NADH binding domain. Composed of six 40-kDa subunits, each of which contains a [2Fe-2S] cluster. Composed of three subunits: 100 kDa structural subunit, 75 kDa subunit with a molybdopterin center, and 50 kDa subunit with FAD and an NADH binding domain.

b) Explain the key features of the Langmuir adsorption model - Drawing a diagram with empty and occupied sites. Show how new molecules would adsorb. drawing the diagram, showing free and empty sites, and their number (to use for next section) - Define the capacity and binding affinity parameters in terms of things shown on the diagram Defining the capacity and binding affinity parameters in terms of bound, free sites, and free molecules - Plot what would be a typical breakthrough curve and give an explanation approximately when breakthrough would occur plotting a typical sigmoidal breakthrough curve and saying it would certainly occur by the time capacity is used, but also could be much earlier if the affinity is low

Water at 20°C flows at a steady average velocity of 5.25 m/s through a smooth pipe of diameter 5.08 cm. The flow is fully developed through the entire section of pipe. The total pipe length is 10.56 m, and there are two 90' elbows. Determine the friction coefficient and the head loss due to friction per meter length of the pipe. Control volume Prepared by Engr.
